Least Common Multiple of 647/11,767/28,221/140

Given numbers are 647/11,767/28,221/140

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 647,767,221

Least Common Multiple of Numerators i.e. LCM of 647,767,221 is 8436233.

GCF of Denominators means GCF of 11,28,140 as per the given fractions.

GCF of 11,28,140 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 647,767,221

LCM of Fractions 647/11,767/28,221/140 is 8436233

13 647, 767, 221
647, 59, 17

∴ So the LCM of the given numbers is 13 x 647 x 59 x 17 = 8436233

Least Common Multiple of 647,767,221 with GCF Formula

Least Common Multiple of 647,767,221 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 647,767,221 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(647,767,221) = 1

common factors(in case of two or more numbers have common factors) = 13

GCF(647,767,221) x common factors =1 x 13 = 13

LCM(647,767,221) = ( 647 × 767 × 221 ) / 13

LCM(647,767,221) = 109671029 / 13

LCM(647,767,221) = 8436233


Lets's calculate GCF of 11,28,140

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 8436233/1

Therefore the LCM of Fractions 647/11,767/28,221/140 is 8436233
