Least Common Multiple of 42/397,64/767,440/936

Given numbers are 42/397,64/767,440/936

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 42,64,440

Least Common Multiple of Numerators i.e. LCM of 42,64,440 is 73920.

GCF of Denominators means GCF of 397,767,936 as per the given fractions.

GCF of 397,767,936 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 42,64,440

LCM of Fractions 42/397,64/767,440/936 is 73920

2 42, 64, 440
2 21, 32, 220
2 21, 16, 110
21, 8, 55

∴ So the LCM of the given numbers is 2 x 2 x 2 x 21 x 8 x 55 = 73920

Least Common Multiple of 42,64,440 with GCF Formula

Least Common Multiple of 42,64,440 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 42,64,440 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,64,440) = 2

common factors(in case of two or more numbers have common factors) = 8

GCF(42,64,440) x common factors =2 x 8 = 16

LCM(42,64,440) = ( 42 × 64 × 440 ) / 16

LCM(42,64,440) = 1182720 / 16

LCM(42,64,440) = 73920


Lets's calculate GCF of 397,767,936

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 73920/1

Therefore the LCM of Fractions 42/397,64/767,440/936 is 73920
