Least Common Multiple of 84/47,74/30,322/257

Given numbers are 84/47,74/30,322/257

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 84,74,322

Least Common Multiple of Numerators i.e. LCM of 84,74,322 is 71484.

GCF of Denominators means GCF of 47,30,257 as per the given fractions.

GCF of 47,30,257 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 84,74,322

LCM of Fractions 84/47,74/30,322/257 is 71484

2 84, 74, 322
7 42, 37, 161
6, 37, 23

∴ So the LCM of the given numbers is 2 x 7 x 6 x 37 x 23 = 71484

Least Common Multiple of 84,74,322 with GCF Formula

Least Common Multiple of 84,74,322 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 84,74,322 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(84,74,322) = 2

common factors(in case of two or more numbers have common factors) = 14

GCF(84,74,322) x common factors =2 x 14 = 28

LCM(84,74,322) = ( 84 × 74 × 322 ) / 28

LCM(84,74,322) = 2001552 / 28

LCM(84,74,322) = 71484


Lets's calculate GCF of 47,30,257

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 71484/1

Therefore the LCM of Fractions 84/47,74/30,322/257 is 71484
