Least Common Multiple of 61/28,68/74,105/641

Given numbers are 61/28,68/74,105/641

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 61,68,105

Least Common Multiple of Numerators i.e. LCM of 61,68,105 is 435540.

GCF of Denominators means GCF of 28,74,641 as per the given fractions.

GCF of 28,74,641 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 61,68,105

LCM of Fractions 61/28,68/74,105/641 is 435540

Given numbers has no common factors except 1. So, there LCM is their product i.e 435540

Least Common Multiple of 61,68,105 with GCF Formula

Least Common Multiple of 61,68,105 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 61,68,105 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(61,68,105) = 1

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

GCF(61,68,105) x common factors =1 x 1 = 1

LCM(61,68,105) = ( 61 × 68 × 105 ) / 1

LCM(61,68,105) = 435540 / 1

LCM(61,68,105) = 435540


Lets's calculate GCF of 28,74,641

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 435540/1

Therefore the LCM of Fractions 61/28,68/74,105/641 is 435540
