Least Common Multiple of 21/47,24/646,905/915

Given numbers are 21/47,24/646,905/915

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 21,24,905

Least Common Multiple of Numerators i.e. LCM of 21,24,905 is 152040.

GCF of Denominators means GCF of 47,646,915 as per the given fractions.

GCF of 47,646,915 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 21,24,905

LCM of Fractions 21/47,24/646,905/915 is 152040

3 21, 24, 905
7, 8, 905

∴ So the LCM of the given numbers is 3 x 7 x 8 x 905 = 152040

Least Common Multiple of 21,24,905 with GCF Formula

Least Common Multiple of 21,24,905 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 21,24,905 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,24,905) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(21,24,905) x common factors =1 x 3 = 3

LCM(21,24,905) = ( 21 × 24 × 905 ) / 3

LCM(21,24,905) = 456120 / 3

LCM(21,24,905) = 152040


Lets's calculate GCF of 47,646,915

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 152040/1

Therefore the LCM of Fractions 21/47,24/646,905/915 is 152040
