Least Common Multiple of 70/21,372/13,860/87

Given numbers are 70/21,372/13,860/87

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 70,372,860

Least Common Multiple of Numerators i.e. LCM of 70,372,860 is 559860.

GCF of Denominators means GCF of 21,13,87 as per the given fractions.

GCF of 21,13,87 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 70,372,860

LCM of Fractions 70/21,372/13,860/87 is 559860

2 70, 372, 860
2 35, 186, 430
5 35, 93, 215
7, 93, 43

∴ So the LCM of the given numbers is 2 x 2 x 5 x 7 x 93 x 43 = 559860

Least Common Multiple of 70,372,860 with GCF Formula

Least Common Multiple of 70,372,860 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 70,372,860 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,372,860) = 2

common factors(in case of two or more numbers have common factors) = 20

GCF(70,372,860) x common factors =2 x 20 = 40

LCM(70,372,860) = ( 70 × 372 × 860 ) / 40

LCM(70,372,860) = 22394400 / 40

LCM(70,372,860) = 559860


Lets's calculate GCF of 21,13,87

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 559860/1

Therefore the LCM of Fractions 70/21,372/13,860/87 is 559860
