LCM of:

Least Common Multiple of 21/71,315/79,481/316

Given numbers are 21/71,315/79,481/316

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 21,315,481

Least Common Multiple of Numerators i.e. LCM of 21,315,481 is 151515.

GCF of Denominators means GCF of 71,79,316 as per the given fractions.

GCF of 71,79,316 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 21,315,481

LCM of Fractions 21/71,315/79,481/316 is 151515

3 21, 315, 481
7 7, 105, 481
1, 15, 481

∴ So the LCM of the given numbers is 3 x 7 x 1 x 15 x 481 = 151515

Least Common Multiple of 21,315,481 with GCF Formula

Least Common Multiple of 21,315,481 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 21,315,481 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,315,481) = 1

common factors(in case of two or more numbers have common factors) = 21

GCF(21,315,481) x common factors =1 x 21 = 21

LCM(21,315,481) = ( 21 × 315 × 481 ) / 21

LCM(21,315,481) = 3181815 / 21

LCM(21,315,481) = 151515


Lets's calculate GCF of 71,79,316

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 151515/1

Therefore the LCM of Fractions 21/71,315/79,481/316 is 151515
