Lets's calculate LCM of 99,65,724

Given numbers has no common factors except 1. So, there LCM is their product i.e 4658940

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/4658940

Therefore, the GCF of Fractions 90/99,84/65,138/724 is 6/4658940

Least Common Multiple of 99,65,724 with GCF Formula

Least Common Multiple of 99,65,724 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 99,65,724 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(99,65,724) = 1

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

GCF(99,65,724) x common factors =1 x 1 = 1

LCM(99,65,724) = ( 99 × 65 × 724 ) / 1

LCM(99,65,724) = 4658940 / 1

LCM(99,65,724) = 4658940
