	1, 1, 4, 115

∴ So the LCM of the given numbers is 2 x 3 x 3 x 3 x 3 x 1 x 1 x 4 x 115 = 74520

Least Common Multiple of 81,81,24,690 with GCF Formula

The formula of LCM is LCM(a₁,a₂,a₃....,a_n) = ( a₁ × a₂ × a₃ × .... × a_n) / GCF(a₁,a₂,a₃....,a_n) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 81,81,24,690 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,81,24,690) = 3

common factors(in case of two or more numbers have common factors) = 486

GCF(81,81,24,690) x common factors =3 x 486 = 1458

LCM(81,81,24,690) = ( 81 × 81 × 24 × 690 ) / 1458

LCM(81,81,24,690) = 108650160 / 1458

LCM(81,81,24,690) = 74520

∴ Least Common Multiple of 81,81,24,690 is 74520
