Least Common Multiple of 87/56,780/79,455/328

Given numbers are 87/56,780/79,455/328

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 87,780,455

Least Common Multiple of Numerators i.e. LCM of 87,780,455 is 158340.

GCF of Denominators means GCF of 56,79,328 as per the given fractions.

GCF of 56,79,328 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 87,780,455

LCM of Fractions 87/56,780/79,455/328 is 158340

3 87, 780, 455
5 29, 260, 455
13 29, 52, 91
29, 4, 7

∴ So the LCM of the given numbers is 3 x 5 x 13 x 29 x 4 x 7 = 158340

Least Common Multiple of 87,780,455 with GCF Formula

Least Common Multiple of 87,780,455 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 87,780,455 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(87,780,455) = 1

common factors(in case of two or more numbers have common factors) = 195

GCF(87,780,455) x common factors =1 x 195 = 195

LCM(87,780,455) = ( 87 × 780 × 455 ) / 195

LCM(87,780,455) = 30876300 / 195

LCM(87,780,455) = 158340


Lets's calculate GCF of 56,79,328

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 158340/1

Therefore the LCM of Fractions 87/56,780/79,455/328 is 158340
