What is the greatest common factor of 72 144 and 216?

Answer 1

To find the greatest common factor (GCF) of 72, 144, and 216, we first need to factorize each number. The prime factorization of 72 is 2^3 * 3^2, 144 is 2^4 * 3^2, and 216 is 2^3 * 3^3. The GCF is found by identifying the common prime factors with the lowest exponents, which in this case are 2^3 * 3^2, resulting in a GCF of 72.

Answer 2

The least common multiple of 72 , 144 , 216 = 432

Answer 3
