Least Common Multiple of 54, 66, 639

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

• Least Common Multiple of 54, 66, 639 by common division method
• Least Common Multiple of 54, 66, 639 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 3 x 3 x 11 x 71 = 42174

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 54,66,639 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(54,66,639) = 3

common factors(in case of two or more numbers have common factors) = 18

GCF(54,66,639) x common factors =3 x 18 = 54

LCM(54,66,639) = ( 54 × 66 × 639 ) / 54

LCM(54,66,639) = 2277396 / 54

LCM(54,66,639) = 42174

∴ Least Common Multiple of 54,66,639 is 42174

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

• LCM of 25, 58, 822
• LCM of 58, 56, 851
• LCM of 31, 38, 617
