Lets's calculate LCM of 42,751

Given numbers has no common factors except 1. So, there LCM is their product i.e 31542

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 14/31542

Therefore, the GCF of Fractions 392/42,2142/751 is 14/31542

Least Common Multiple of 42,751 with GCF Formula

Least Common Multiple of 42,751 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 42,751 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,751) = 1

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

GCF(42,751) x common factors =1 x 1 = 1

LCM(42,751) = ( 42 × 751 ) / 1

LCM(42,751) = 31542 / 1

LCM(42,751) = 31542
