Lets's calculate LCM of 639,158

Given numbers has no common factors except 1. So, there LCM is their product i.e 100962

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/100962

Therefore, the GCF of Fractions 345/639,4971/158 is 3/100962

Least Common Multiple of 639,158 with GCF Formula

Least Common Multiple of 639,158 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 639,158 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(639,158) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(639,158) x common factors =1 x 1 = 1

LCM(639,158) = ( 639 × 158 ) / 1

LCM(639,158) = 100962 / 1

LCM(639,158) = 100962
