Least Common Multiple of 643/985,511/745

Given numbers are 643/985,511/745

Formula to find LCM of Fractions is

LCM = LCM of Numerators/GCF of Denominators

As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators

In the given fractions LCM of Numerators means LCM of 643,511

Least Common Multiple of Numerators i.e. LCM of 643,511 is 328573.

GCF of Denominators means GCF of 985,745 as per the given fractions.

GCF of 985,745 is 5 as it is the largest common factor for these numbers.

Lets's calculate LCM of 643,511

LCM of Fractions 643/985,511/745 is 328573/5

Given numbers has no common factors except 1. So, there LCM is their product i.e 328573

Least Common Multiple of 643,511 with GCF Formula

Least Common Multiple of 643,511 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 643,511 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(643,511) = 1

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

GCF(643,511) x common factors =1 x 1 = 1

LCM(643,511) = ( 643 × 511 ) / 1

LCM(643,511) = 328573 / 1

LCM(643,511) = 328573


Lets's calculate GCF of 985,745

5 985, 745
197, 149

∴ So the GCF of the given numbers is 5 = 5

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 328573/5

Therefore the LCM of Fractions 643/985,511/745 is 328573/5
