Least Common Multiple of 13/98,77/387,278/646

Given numbers are 13/98,77/387,278/646

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 13,77,278

Least Common Multiple of Numerators i.e. LCM of 13,77,278 is 278278.

GCF of Denominators means GCF of 98,387,646 as per the given fractions.

GCF of 98,387,646 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 13,77,278

LCM of Fractions 13/98,77/387,278/646 is 278278

Given numbers has no common factors except 1. So, there LCM is their product i.e 278278

Least Common Multiple of 13,77,278 with GCF Formula

Least Common Multiple of 13,77,278 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 13,77,278 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(13,77,278) = 1

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

GCF(13,77,278) x common factors =1 x 1 = 1

LCM(13,77,278) = ( 13 × 77 × 278 ) / 1

LCM(13,77,278) = 278278 / 1

LCM(13,77,278) = 278278


Lets's calculate GCF of 98,387,646

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 278278/1

Therefore the LCM of Fractions 13/98,77/387,278/646 is 278278
