Least Common Multiple of 721/78,712/11,798/400

Given numbers are 721/78,712/11,798/400

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 721,712,798

Least Common Multiple of Numerators i.e. LCM of 721,712,798 is 29261064.

GCF of Denominators means GCF of 78,11,400 as per the given fractions.

GCF of 78,11,400 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 721,712,798

LCM of Fractions 721/78,712/11,798/400 is 29261064

2 721, 712, 798
7 721, 356, 399
103, 356, 57

∴ So the LCM of the given numbers is 2 x 7 x 103 x 356 x 57 = 29261064

Least Common Multiple of 721,712,798 with GCF Formula

Least Common Multiple of 721,712,798 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 721,712,798 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(721,712,798) = 1

common factors(in case of two or more numbers have common factors) = 14

GCF(721,712,798) x common factors =1 x 14 = 14

LCM(721,712,798) = ( 721 × 712 × 798 ) / 14

LCM(721,712,798) = 409654896 / 14

LCM(721,712,798) = 29261064


Lets's calculate GCF of 78,11,400

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 29261064/1

Therefore the LCM of Fractions 721/78,712/11,798/400 is 29261064
