Least Common Multiple of 18, 15, 585

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

• Least Common Multiple of 18, 15, 585 by common division method
• Least Common Multiple of 18, 15, 585 with GCF Formula

∴ So the LCM of the given numbers is 3 x 3 x 5 x 2 x 1 x 13 = 1170

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 18,15,585 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(18,15,585) = 3

common factors(in case of two or more numbers have common factors) = 45

GCF(18,15,585) x common factors =3 x 45 = 135

LCM(18,15,585) = ( 18 × 15 × 585 ) / 135

LCM(18,15,585) = 157950 / 135

LCM(18,15,585) = 1170

∴ Least Common Multiple of 18,15,585 is 1170

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

• LCM of 67, 13, 926
• LCM of 22, 95, 271
