Question

What is the greatest common factor of 180 and 240

Answer 1

The GCF of 180 and 240 is 60

Answer 2

​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!​​​​
