Lets's calculate LCM of 51,142

Given numbers has no common factors except 1. So, there LCM is their product i.e 7242

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7242

Therefore, the GCF of Fractions 249/51,845/142 is 1/7242

Least Common Multiple of 51,142 with GCF Formula

Least Common Multiple of 51,142 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 51,142 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(51,142) = 1

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

GCF(51,142) x common factors =1 x 1 = 1

LCM(51,142) = ( 51 × 142 ) / 1

LCM(51,142) = 7242 / 1

LCM(51,142) = 7242
