Least Common Multiple of 987, 972, 81

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

• Least Common Multiple of 987, 972, 81 by common division method
• Least Common Multiple of 987, 972, 81 with GCF Formula

∴ So the LCM of the given numbers is 3 x 3 x 3 x 3 x 329 x 12 x 1 = 319788

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 987,972,81 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(987,972,81) = 3

common factors(in case of two or more numbers have common factors) = 81

GCF(987,972,81) x common factors =3 x 81 = 243

LCM(987,972,81) = ( 987 × 972 × 81 ) / 243

LCM(987,972,81) = 77708484 / 243

LCM(987,972,81) = 319788

∴ Least Common Multiple of 987,972,81 is 319788

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