Least Common Multiple of 81/151,145/172,702/870

Given numbers are 81/151,145/172,702/870

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 81,145,702

Least Common Multiple of Numerators i.e. LCM of 81,145,702 is 305370.

GCF of Denominators means GCF of 151,172,870 as per the given fractions.

GCF of 151,172,870 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 81,145,702

LCM of Fractions 81/151,145/172,702/870 is 305370

3 81, 145, 702
3 27, 145, 234
3 9, 145, 78
3, 145, 26

∴ So the LCM of the given numbers is 3 x 3 x 3 x 3 x 145 x 26 = 305370

Least Common Multiple of 81,145,702 with GCF Formula

Least Common Multiple of 81,145,702 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 81,145,702 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,145,702) = 1

common factors(in case of two or more numbers have common factors) = 27

GCF(81,145,702) x common factors =1 x 27 = 27

LCM(81,145,702) = ( 81 × 145 × 702 ) / 27

LCM(81,145,702) = 8244990 / 27

LCM(81,145,702) = 305370


Lets's calculate GCF of 151,172,870

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 305370/1

Therefore the LCM of Fractions 81/151,145/172,702/870 is 305370
