Lets's calculate LCM of 1287,7617

LCM of Fractions 1287/711,7617/9721 is 3267693

3 1287, 7617
429, 2539

∴ So the LCM of the given numbers is 3 x 429 x 2539 = 3267693

Least Common Multiple of 1287,7617 with GCF Formula

Least Common Multiple of 1287,7617 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 1287,7617 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1287,7617) = 3

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

GCF(1287,7617) x common factors =3 x 1 = 3

LCM(1287,7617) = ( 1287 × 7617 ) / 3

LCM(1287,7617) = 9803079 / 3

LCM(1287,7617) = 3267693


Lets's calculate GCF of 711,9721

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3267693/1

Therefore the LCM of Fractions 1287/711,7617/9721 is 3267693
