Lets's calculate LCM of 31,253,947

Given numbers has no common factors except 1. So, there LCM is their product i.e 7427321

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7427321

Therefore, the GCF of Fractions 56/31,72/253,905/947 is 1/7427321

Least Common Multiple of 31,253,947 with GCF Formula

Least Common Multiple of 31,253,947 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 31,253,947 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(31,253,947) = 1

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

GCF(31,253,947) x common factors =1 x 1 = 1

LCM(31,253,947) = ( 31 × 253 × 947 ) / 1

LCM(31,253,947) = 7427321 / 1

LCM(31,253,947) = 7427321
