Lets's calculate LCM of 391,509,913

LCM of Fractions 391/72,509/65,913/84 is 181704347

Given numbers has no common factors except 1. So, there LCM is their product i.e 181704347

Least Common Multiple of 391,509,913 with GCF Formula

Least Common Multiple of 391,509,913 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 391,509,913 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(391,509,913) = 1

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

GCF(391,509,913) x common factors =1 x 1 = 1

LCM(391,509,913) = ( 391 × 509 × 913 ) / 1

LCM(391,509,913) = 181704347 / 1

LCM(391,509,913) = 181704347


Lets's calculate GCF of 72,65,84

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 181704347/1

Therefore the LCM of Fractions 391/72,509/65,913/84 is 181704347
