Least Common Multiple of 15/51,83/874,421/861

Given numbers are 15/51,83/874,421/861

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 15,83,421

Least Common Multiple of Numerators i.e. LCM of 15,83,421 is 524145.

GCF of Denominators means GCF of 51,874,861 as per the given fractions.

GCF of 51,874,861 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 15,83,421

LCM of Fractions 15/51,83/874,421/861 is 524145

Given numbers has no common factors except 1. So, there LCM is their product i.e 524145

Least Common Multiple of 15,83,421 with GCF Formula

Least Common Multiple of 15,83,421 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 15,83,421 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(15,83,421) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(15,83,421) x common factors =1 x 1 = 1

LCM(15,83,421) = ( 15 × 83 × 421 ) / 1

LCM(15,83,421) = 524145 / 1

LCM(15,83,421) = 524145


Lets's calculate GCF of 51,874,861

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 524145/1

Therefore the LCM of Fractions 15/51,83/874,421/861 is 524145
