Lets's calculate LCM of 647,721,734

LCM of Fractions 647/89,721/86,734/79 is 342401458

Given numbers has no common factors except 1. So, there LCM is their product i.e 342401458

Least Common Multiple of 647,721,734 with GCF Formula

Least Common Multiple of 647,721,734 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 647,721,734 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(647,721,734) = 1

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

GCF(647,721,734) x common factors =1 x 1 = 1

LCM(647,721,734) = ( 647 × 721 × 734 ) / 1

LCM(647,721,734) = 342401458 / 1

LCM(647,721,734) = 342401458


Lets's calculate GCF of 89,86,79

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 342401458/1

Therefore the LCM of Fractions 647/89,721/86,734/79 is 342401458
