Least Common Multiple of 84/64,40/79,197/253

Given numbers are 84/64,40/79,197/253

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 84,40,197

Least Common Multiple of Numerators i.e. LCM of 84,40,197 is 165480.

GCF of Denominators means GCF of 64,79,253 as per the given fractions.

GCF of 64,79,253 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 84,40,197

LCM of Fractions 84/64,40/79,197/253 is 165480

2 84, 40, 197
2 42, 20, 197
21, 10, 197

∴ So the LCM of the given numbers is 2 x 2 x 21 x 10 x 197 = 165480

Least Common Multiple of 84,40,197 with GCF Formula

Least Common Multiple of 84,40,197 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 84,40,197 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(84,40,197) = 1

common factors(in case of two or more numbers have common factors) = 4

GCF(84,40,197) x common factors =1 x 4 = 4

LCM(84,40,197) = ( 84 × 40 × 197 ) / 4

LCM(84,40,197) = 661920 / 4

LCM(84,40,197) = 165480


Lets's calculate GCF of 64,79,253

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 165480/1

Therefore the LCM of Fractions 84/64,40/79,197/253 is 165480
