Least Common Multiple of 42, 54, 504

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

• Least Common Multiple of 42, 54, 504 by common division method
• Least Common Multiple of 42, 54, 504 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 3 x 7 x 1 x 3 x 4 = 1512

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 42,54,504 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,54,504) = 6

common factors(in case of two or more numbers have common factors) = 126

GCF(42,54,504) x common factors =6 x 126 = 756

LCM(42,54,504) = ( 42 × 54 × 504 ) / 756

LCM(42,54,504) = 1143072 / 756

LCM(42,54,504) = 1512

∴ Least Common Multiple of 42,54,504 is 1512

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

• LCM of 80, 55, 174
• LCM of 28, 30, 177
