Lets's calculate LCM of 31,55,862

Given numbers has no common factors except 1. So, there LCM is their product i.e 1469710

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1469710

Therefore, the GCF of Fractions 87/31,406/55,165/862 is 1/1469710

Least Common Multiple of 31,55,862 with GCF Formula

Least Common Multiple of 31,55,862 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 31,55,862 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(31,55,862) = 1

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

GCF(31,55,862) x common factors =1 x 1 = 1

LCM(31,55,862) = ( 31 × 55 × 862 ) / 1

LCM(31,55,862) = 1469710 / 1

LCM(31,55,862) = 1469710
