The GCF of 12 and 18 is 6.

Front

Find the GCF of 24, 36, and 60.

Back

The GCF of 24, 36, and 60 is 12.

Front

What is the relationship between GCF and LCM (Least Common Multiple)?

Back

The product of the GCF and LCM of two numbers is equal to the product of the numbers themselves.

Front

How can prime factorization help in finding the GCF?

Back

By breaking down each number into its prime factors, the GCF can be found by multiplying the lowest powers of common prime factors.
