Lets's calculate LCM of 881,319,513

Given numbers has no common factors except 1. So, there LCM is their product i.e 144173007

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 42/144173007

Therefore, the GCF of Fractions 84/881,42/319,840/513 is 42/144173007

Least Common Multiple of 881,319,513 with GCF Formula

Least Common Multiple of 881,319,513 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 881,319,513 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(881,319,513) = 1

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

GCF(881,319,513) x common factors =1 x 1 = 1

LCM(881,319,513) = ( 881 × 319 × 513 ) / 1

LCM(881,319,513) = 144173007 / 1

LCM(881,319,513) = 144173007
