∙ 8y agoThe GCF of 12, 18, and 60 is 6.
First, the GCF can't be larger than the smallest difference between the numbers, which is 6 (12-18). Noticing that 6 is a factor of all three numbers in the set, we then know it is the GCF.
You can also write down the prime factorizations of the numbers in the set:
The prime factorization of 12 is 2*2*3
The prime factorization of 18 is 2*3*3
The prime factorization of 60 is 2*2*3*5
The common prime factors are 2*3 = 6, so that's the GCF.
