Least Common Multiple of 21/865,138/91,574/595

Given numbers are 21/865,138/91,574/595

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 21,138,574

Least Common Multiple of Numerators i.e. LCM of 21,138,574 is 39606.

GCF of Denominators means GCF of 865,91,595 as per the given fractions.

GCF of 865,91,595 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 21,138,574

LCM of Fractions 21/865,138/91,574/595 is 39606

2 21, 138, 574
3 21, 69, 287
7 7, 23, 287
1, 23, 41

∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 23 x 41 = 39606

Least Common Multiple of 21,138,574 with GCF Formula

Least Common Multiple of 21,138,574 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 21,138,574 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,138,574) = 1

common factors(in case of two or more numbers have common factors) = 42

GCF(21,138,574) x common factors =1 x 42 = 42

LCM(21,138,574) = ( 21 × 138 × 574 ) / 42

LCM(21,138,574) = 1663452 / 42

LCM(21,138,574) = 39606


Lets's calculate GCF of 865,91,595

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 39606/1

Therefore the LCM of Fractions 21/865,138/91,574/595 is 39606
