Least Common Multiple of 38, 81, 81, 54

Least common multiple or lowest common denominator (lcd) can be calculated in three ways

• Least Common Multiple of 38, 81, 81, 54 by common division method
• Least Common Multiple of 38, 81, 81, 54 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 3 x 3 x 3 x 19 x 1 x 1 x 1 = 3078

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 38,81,81,54 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(38,81,81,54) = 1

common factors(in case of two or more numbers have common factors) = 4374

GCF(38,81,81,54) x common factors =1 x 4374 = 4374

LCM(38,81,81,54) = ( 38 × 81 × 81 × 54 ) / 4374

LCM(38,81,81,54) = 13463172 / 4374

LCM(38,81,81,54) = 3078

∴ Least Common Multiple of 38,81,81,54 is 3078

Here are some samples of LCM of two or more Numbers calculations.
