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 981,1257

Least Common Multiple of Numerators i.e. LCM of 981,1257 is 411039.

GCF of Denominators means GCF of 170,749 as per the given fractions.

GCF of 170,749 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 981,1257

LCM of Fractions 981/170,1257/749 is 411039

3 981, 1257
327, 419

∴ So the LCM of the given numbers is 3 x 327 x 419 = 411039

Least Common Multiple of 981,1257 with GCF Formula

Least Common Multiple of 981,1257 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 981,1257 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(981,1257) = 3

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

GCF(981,1257) x common factors =3 x 1 = 3

LCM(981,1257) = ( 981 × 1257 ) / 3

LCM(981,1257) = 1233117 / 3

LCM(981,1257) = 411039


Lets's calculate GCF of 170,749

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 411039/1

Therefore the LCM of Fractions 981/170,1257/749 is 411039
