Least Common Multiple of 54, 18, 438

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

• Least Common Multiple of 54, 18, 438 by common division method
• Least Common Multiple of 54, 18, 438 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 3 x 1 x 3 x 73 = 3942

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 54,18,438 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(54,18,438) = 6

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

GCF(54,18,438) x common factors =6 x 18 = 108

LCM(54,18,438) = ( 54 × 18 × 438 ) / 108

LCM(54,18,438) = 425736 / 108

LCM(54,18,438) = 3942

∴ Least Common Multiple of 54,18,438 is 3942

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

• LCM of 98, 15, 273
• LCM of 77, 60, 889
