Lets's calculate LCM of 25,16,637

Given numbers has no common factors except 1. So, there LCM is their product i.e 254800

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/254800

Therefore, the GCF of Fractions 31/25,31/16,42/637 is 1/254800

Least Common Multiple of 25,16,637 with GCF Formula

Least Common Multiple of 25,16,637 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 25,16,637 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(25,16,637) = 1

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

GCF(25,16,637) x common factors =1 x 1 = 1

LCM(25,16,637) = ( 25 × 16 × 637 ) / 1

LCM(25,16,637) = 254800 / 1

LCM(25,16,637) = 254800
