Least Common Multiple of 57/21,32/87,808/974

Given numbers are 57/21,32/87,808/974

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 57,32,808

Least Common Multiple of Numerators i.e. LCM of 57,32,808 is 184224.

GCF of Denominators means GCF of 21,87,974 as per the given fractions.

GCF of 21,87,974 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 57,32,808

LCM of Fractions 57/21,32/87,808/974 is 184224

2 57, 32, 808
2 57, 16, 404
2 57, 8, 202
57, 4, 101

∴ So the LCM of the given numbers is 2 x 2 x 2 x 57 x 4 x 101 = 184224

Least Common Multiple of 57,32,808 with GCF Formula

Least Common Multiple of 57,32,808 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 57,32,808 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(57,32,808) = 1

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

GCF(57,32,808) x common factors =1 x 8 = 8

LCM(57,32,808) = ( 57 × 32 × 808 ) / 8

LCM(57,32,808) = 1473792 / 8

LCM(57,32,808) = 184224


Lets's calculate GCF of 21,87,974

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 184224/1

Therefore the LCM of Fractions 57/21,32/87,808/974 is 184224
