GCF of 98,13,40 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 638,655,291

LCM of Fractions 638/98,655/13,291/40 is 121605990

Given numbers has no common factors except 1. So, there LCM is their product i.e 121605990

Least Common Multiple of 638,655,291 with GCF Formula

Least Common Multiple of 638,655,291 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 638,655,291 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(638,655,291) = 1

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

GCF(638,655,291) x common factors =1 x 1 = 1

LCM(638,655,291) = ( 638 × 655 × 291 ) / 1

LCM(638,655,291) = 121605990 / 1

LCM(638,655,291) = 121605990


Lets's calculate GCF of 98,13,40

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 121605990/1

Therefore the LCM of Fractions 638/98,655/13,291/40 is 121605990
