Lets's calculate LCM of 387,4812

LCM of Fractions 387/81,4812/180 is 68972

3 387, 4812
129, 1604

∴ So the LCM of the given numbers is 3 x 129 x 1604 = 620748

Least Common Multiple of 387,4812 with GCF Formula

Least Common Multiple of 387,4812 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 387,4812 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(387,4812) = 3

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

GCF(387,4812) x common factors =3 x 1 = 3

LCM(387,4812) = ( 387 × 4812 ) / 3

LCM(387,4812) = 1862244 / 3

LCM(387,4812) = 620748


Lets's calculate GCF of 81,180

3 81, 180
3 27, 60
9, 20

∴ So the GCF of the given numbers is 3 x 3 = 9

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 620748/9

Therefore the LCM of Fractions 387/81,4812/180 is 68972
