Prime factorization of each: 84 = 22*3*7 125=53 So, these numbers are relatively prime and GCF=1.
22 x 3 x 7 = 84
The GCF of 84 and 156 is 12.First, find the prime factors:84 = 2*2*3*7156 = 2*2*3*13Then, to determine the gcf, multiply the shared prime factors:GCF = 2*2*3 = 12
The prime factorization of 84 is 2 x 2 x 3 x 7.
2 x 2 x 2 x 3 = 24 2 x 2 x 3 x 7 = 84 2 x 2 x 2 x 3 x 7 = 168, the LCM
