Least Common Multiple of 90, 72, 900

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

• Least Common Multiple of 90, 72, 900 by common division method
• Least Common Multiple of 90, 72, 900 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 5 x 1 x 2 x 5 = 1800

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 90,72,900 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(90,72,900) = 18

common factors(in case of two or more numbers have common factors) = 180

GCF(90,72,900) x common factors =18 x 180 = 3240

LCM(90,72,900) = ( 90 × 72 × 900 ) / 3240

LCM(90,72,900) = 5832000 / 3240

LCM(90,72,900) = 1800

∴ Least Common Multiple of 90,72,900 is 1800

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

• LCM of 82, 73, 409
• LCM of 26, 56, 610
• LCM of 61, 58, 551
• LCM of 40, 43, 946
