Lets's calculate LCM of 67,91,656

LCM of Fractions 67/420,91/635,656/637 is 3999632

Given numbers has no common factors except 1. So, there LCM is their product i.e 3999632

Least Common Multiple of 67,91,656 with GCF Formula

Least Common Multiple of 67,91,656 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 67,91,656 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(67,91,656) = 1

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

GCF(67,91,656) x common factors =1 x 1 = 1

LCM(67,91,656) = ( 67 × 91 × 656 ) / 1

LCM(67,91,656) = 3999632 / 1

LCM(67,91,656) = 3999632


Lets's calculate GCF of 420,635,637

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3999632/1

Therefore the LCM of Fractions 67/420,91/635,656/637 is 3999632
