Least Common Multiple of 27, 27, 17, 81

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

• Least Common Multiple of 27, 27, 17, 81 by common division method
• Least Common Multiple of 27, 27, 17, 81 with GCF Formula

∴ So the LCM of the given numbers is 3 x 3 x 3 x 1 x 1 x 17 x 3 = 1377

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 27,27,17,81 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(27,27,17,81) = 1

common factors(in case of two or more numbers have common factors) = 729

GCF(27,27,17,81) x common factors =1 x 729 = 729

LCM(27,27,17,81) = ( 27 × 27 × 17 × 81 ) / 729

LCM(27,27,17,81) = 1003833 / 729

LCM(27,27,17,81) = 1377

∴ Least Common Multiple of 27,27,17,81 is 1377

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