Least Common Multiple of 68/42,411/18,757/137

Given numbers are 68/42,411/18,757/137

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 68,411,757

Least Common Multiple of Numerators i.e. LCM of 68,411,757 is 21156636.

GCF of Denominators means GCF of 42,18,137 as per the given fractions.

GCF of 42,18,137 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 68,411,757

LCM of Fractions 68/42,411/18,757/137 is 21156636

Given numbers has no common factors except 1. So, there LCM is their product i.e 21156636

Least Common Multiple of 68,411,757 with GCF Formula

Least Common Multiple of 68,411,757 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 68,411,757 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(68,411,757) = 1

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

GCF(68,411,757) x common factors =1 x 1 = 1

LCM(68,411,757) = ( 68 × 411 × 757 ) / 1

LCM(68,411,757) = 21156636 / 1

LCM(68,411,757) = 21156636


Lets's calculate GCF of 42,18,137

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 21156636/1

Therefore the LCM of Fractions 68/42,411/18,757/137 is 21156636
