What is the greatest common factor for 60 and 45

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

First we have to find the prime factorization of 60

60 = 2² × 3 × 5

Then we have to find the prime factorization of 45

45 = 3² × 5

Now we have to multiply the common factors to both numbers with a lower exponent

GCF = 3 × 5 = 15

Answer : GCF(60,45) = 15
