LCM of:

### Least Common Multiple (LCM) of 63,81,108,120 By Common Division

 2 63, 81, 108, 120 2 63, 81, 54, 60 3 63, 81, 27, 30 3 21, 9, 27, 10 3 7, 3, 9, 10 7, 1, 3, 10

∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 3 x 7 x 1 x 3 x 10 = 22680

### Least Common Multiple of 63,81,108,120 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 63,81,108,120 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(63,81,108,120) = 3

common factors(in case of two or more numbers have common factors) = 972

GCF(63,81,108,120) x common factors =3 x 972 = 2916

LCM(63,81,108,120) = ( 63 × 81 × 108 × 120 ) / 2916

LCM(63,81,108,120) = 66134880 / 2916

LCM(63,81,108,120) = 22680

∴ Least Common Multiple of 63,81,108,120 is 22680
