LCM of:

Least Common Multiple of 13/70,77/891,721/894

Given numbers are 13/70,77/891,721/894

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 13,77,721

Least Common Multiple of Numerators i.e. LCM of 13,77,721 is 103103.

GCF of Denominators means GCF of 70,891,894 as per the given fractions.

GCF of 70,891,894 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 13,77,721

LCM of Fractions 13/70,77/891,721/894 is 103103

7 13, 77, 721
13, 11, 103

∴ So the LCM of the given numbers is 7 x 13 x 11 x 103 = 103103

Least Common Multiple of 13,77,721 with GCF Formula

Least Common Multiple of 13,77,721 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 13,77,721 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(13,77,721) = 1

common factors(in case of two or more numbers have common factors) = 7

GCF(13,77,721) x common factors =1 x 7 = 7

LCM(13,77,721) = ( 13 × 77 × 721 ) / 7

LCM(13,77,721) = 721721 / 7

LCM(13,77,721) = 103103


Lets's calculate GCF of 70,891,894

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 103103/1

Therefore the LCM of Fractions 13/70,77/891,721/894 is 103103
