Least Common Multiple of 72/845,456/419,472/655

Given numbers are 72/845,456/419,472/655

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 72,456,472

Least Common Multiple of Numerators i.e. LCM of 72,456,472 is 80712.

GCF of Denominators means GCF of 845,419,655 as per the given fractions.

GCF of 845,419,655 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 72,456,472

LCM of Fractions 72/845,456/419,472/655 is 80712

2 72, 456, 472
2 36, 228, 236
2 18, 114, 118
3 9, 57, 59
3, 19, 59

∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 3 x 19 x 59 = 80712

Least Common Multiple of 72,456,472 with GCF Formula

Least Common Multiple of 72,456,472 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 72,456,472 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(72,456,472) = 8

common factors(in case of two or more numbers have common factors) = 24

GCF(72,456,472) x common factors =8 x 24 = 192

LCM(72,456,472) = ( 72 × 456 × 472 ) / 192

LCM(72,456,472) = 15496704 / 192

LCM(72,456,472) = 80712


Lets's calculate GCF of 845,419,655

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 80712/1

Therefore the LCM of Fractions 72/845,456/419,472/655 is 80712
