What is the greatest common factor of 180 and 240

The greatest common factor (GCF) is also known as greatest common divisor (GCD).

First we have to find the prime factorization of 180

180 = 2² × 3² × 5

Then we have to find the prime factorization of 240

240 = 2⁴ × 3 × 5

Now we have to multiply the common factors to both numbers with less exponent.

GCF = 2² × 3 × 5 = 60

Answer : GCF(180,240) = 60

Hope this helps!
