Least Common Multiple of 20, 54, 60

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

• Least Common Multiple of 20, 54, 60 by common division method
• Least Common Multiple of 20, 54, 60 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 1 x 9 x 1 = 540

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 20,54,60 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,54,60) = 2

common factors(in case of two or more numbers have common factors) = 60

GCF(20,54,60) x common factors =2 x 60 = 120

LCM(20,54,60) = ( 20 × 54 × 60 ) / 120

LCM(20,54,60) = 64800 / 120

LCM(20,54,60) = 540

∴ Least Common Multiple of 20,54,60 is 540

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

• LCM of 51, 48, 43
• LCM of 64, 67, 97
• LCM of 45, 68, 40
• LCM of 84, 58, 19
