The least common multiple of two numbers is the product of those two numbers divided by their greatest common factor. It the two numbers are coprime (or relatively prime), their greatest common factor is 1. Therefore, their least common multiple is a x b ÷ GCF (of a and b) = a x b ÷ 1 = a x b. The least common multiple of two coprime numbers is the numbers multiplied together.

Multiplying two numbers together will create a common multiple. It is sometimes, but not always, the LCM as well.

The greatest common factor, or GCF, is the largest positive integer that will divide evenly with no remainder into all the members of a given set of numbers. The least common multiple, or LCM, is the smallest positive integer that all the members of a given set of numbers will divide into evenly with no remainder. The product of those two numbers is the answer when they are multiplied together.

If two numbers have no common factor greater then one, then their LCM is the two numbers multiplied together. Example: 9 and 14 have no common factors. Their LCM is 9 x 14, which is 126.

The LCM of prime numbers is simply their product (a x b, or x*y). The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of two prime numbers is 1. Therefore, the least common multiple of two prime numbers is the two numbers multiplied together, since dividing by 1 will not change the answer. The same applies to "relatively prime" numbers such as 10 and 21, where the GCF is also 1.

There is always going to be a LCM. Just multiply the two numbers together to get the a common multiple if you cant find one because the two numbers multiplied together is a common multiple.

The greatest common factor of 11 is 11 itself. This is because the only whole numbers that can be multiplied in order to come up with the number 11 are 1 and 11.

There is no "greatest common multiple" of any two numbers. Whatever their product is, it can be multiplied by any positive integer to yield an even greater number that is also a multiple of the first two. Thus, the number of multiples is infinite.

You do not. To have a greatest common factor, you need two or more numbers. A common factor is a factor that two or more number have in common. However, the prime factorization of all the numbers will help you find the greatest common factor. The greatest common factor will be the prime factors they have in common multiplied together. Example: The prime factors of 45 are 3, 3, and 5. The prime factors of 60 are 2, 2, 3, and 5. The common prime factors are 3 and 5, so the greatest common factor is 3 x 5 = 15.

I love math! It's 2, because its the highest number that can be multiplied into those numbers.

The greatest factor that two or more numbers have in common is known as the greatest common factor, or GCF.

The abbreviation "GCF" means Greatest Common Factor. A GCF is the highest number that can be multiplied that two numbers have in common. An example is that the number 4 is the GCF of 8 and 12. That means when you are comparing the numbers 8 and 12, the highest number that they share that can be multiplied to equal either 8 or 12, is 4.

The least common factor of any set of integers is 1. If the numbers are co-prime, then the greatest common factor will also be 1 and thus the least and greatest common factors will be the same.

If there's only one prime common to the numbers, that's the GCF. If there's more than one, multiply them together. That's the GCF.

You do not. To have a greatest common factor, you need two or more numbers. A common factor is a factor that two or more number have in common. However, the prime factorization of all the numbers will help you find the greatest common factor. The greatest common factor will be the prime factors they have in common multiplied together. Example: The prime factorization of 30135 is 3 x 5 x 7 x 7 x 41. The prime factorization of 98 is 2 x 7 x 7. The prime factors they have in common are 7 and 7, so the greatest common factor is 7 x 7 = 49.

Greatest Common Factor is 1, since 3 and 7 are both prime numbers which means that they can only be equaled when multiplied by one.

The GCD is found by finding all the prime numbers that divide into each that multiplied together give the original number.

To get the greatest common factor you must multiply the two numbers together, in this case giving you 156.

The greatest common multiple of any set of numbers is infinite. The greatest common multiple of any set of numbers will never be one.

The greatest common multiple of any two numbers is infinite.

There is no such thing as a greatest common multiple for any numbers. There is a greatest common divisor and that is 2.

No. There is not a greatest common factor of a single number, such as 37, because there cannot be a greatest common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common.

No, two odd numbers cannot have a greatest common factor that is an even number, because no odd number can have an even number as a factor. Any even number multiplied by any other whole number is always an even number.

Yes, the least common multiple of two numbers is always divisible by those numbers' greatest common factor.

The GCF of 21 and 90 is 3.
