Least Common Multiple of 69/43,86/47,217/31

Given numbers are 69/43,86/47,217/31

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 69,86,217

Least Common Multiple of Numerators i.e. LCM of 69,86,217 is 1287678.

GCF of Denominators means GCF of 43,47,31 as per the given fractions.

GCF of 43,47,31 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 69,86,217

LCM of Fractions 69/43,86/47,217/31 is 1287678

Given numbers has no common factors except 1. So, there LCM is their product i.e 1287678

Least Common Multiple of 69,86,217 with GCF Formula

Least Common Multiple of 69,86,217 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 69,86,217 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(69,86,217) = 1

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

GCF(69,86,217) x common factors =1 x 1 = 1

LCM(69,86,217) = ( 69 × 86 × 217 ) / 1

LCM(69,86,217) = 1287678 / 1

LCM(69,86,217) = 1287678


Lets's calculate GCF of 43,47,31

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1287678/1

Therefore the LCM of Fractions 69/43,86/47,217/31 is 1287678
