Lets's calculate LCM of 861,387

LCM of Fractions 861/432,387/636 is 111069/12

3 861, 387
287, 129

∴ So the LCM of the given numbers is 3 x 287 x 129 = 111069

Least Common Multiple of 861,387 with GCF Formula

Least Common Multiple of 861,387 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 861,387 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(861,387) = 3

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

GCF(861,387) x common factors =3 x 1 = 3

LCM(861,387) = ( 861 × 387 ) / 3

LCM(861,387) = 333207 / 3

LCM(861,387) = 111069


Lets's calculate GCF of 432,636

2 432, 636
2 216, 318
3 108, 159
36, 53

∴ So the GCF of the given numbers is 2 x 2 x 3 = 12

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 111069/12

Therefore the LCM of Fractions 861/432,387/636 is 111069/12
