Least Common Multiple of 1281/785,2715/454

Given numbers are 1281/785,2715/454

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 1281,2715

Least Common Multiple of Numerators i.e. LCM of 1281,2715 is 1159305.

GCF of Denominators means GCF of 785,454 as per the given fractions.

GCF of 785,454 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 1281,2715

LCM of Fractions 1281/785,2715/454 is 1159305

3 1281, 2715
427, 905

∴ So the LCM of the given numbers is 3 x 427 x 905 = 1159305

Least Common Multiple of 1281,2715 with GCF Formula

Least Common Multiple of 1281,2715 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 1281,2715 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1281,2715) = 3

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

GCF(1281,2715) x common factors =3 x 1 = 3

LCM(1281,2715) = ( 1281 × 2715 ) / 3

LCM(1281,2715) = 3477915 / 3

LCM(1281,2715) = 1159305


Lets's calculate GCF of 785,454

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1159305/1

Therefore the LCM of Fractions 1281/785,2715/454 is 1159305
