Least Common Multiple of 78/79,17/812,815/247

Given numbers are 78/79,17/812,815/247

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 78,17,815

Least Common Multiple of Numerators i.e. LCM of 78,17,815 is 1080690.

GCF of Denominators means GCF of 79,812,247 as per the given fractions.

GCF of 79,812,247 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 78,17,815

LCM of Fractions 78/79,17/812,815/247 is 1080690

Given numbers has no common factors except 1. So, there LCM is their product i.e 1080690

Least Common Multiple of 78,17,815 with GCF Formula

Least Common Multiple of 78,17,815 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 78,17,815 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,17,815) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(78,17,815) x common factors =1 x 1 = 1

LCM(78,17,815) = ( 78 × 17 × 815 ) / 1

LCM(78,17,815) = 1080690 / 1

LCM(78,17,815) = 1080690


Lets's calculate GCF of 79,812,247

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1080690/1

Therefore the LCM of Fractions 78/79,17/812,815/247 is 1080690
