How are lcm and gcf alike?

Answer 1

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. Factors go into numbers, numbers go into multiples.

Answer 2

In each of these, you are best to start out finding the prime factors.

Answer 3

For both GCF and LCM you find something in common.

Answer 4

To find both you start by doing a prime factorization, but then you do something a little different.

Answer 5

The product of the LCM and GCF of two numbers equals the product of the two numbers.

Answer 6

GCF and LCM are similar because you need to find the prime factorizations of the two numbers in both cases to get the result.

Answer 7

The product of the GCF and LCM of two numbers is the same as the product of the two numbers.
