Least Common Multiple of 420, 290, 812

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

• Least Common Multiple of 420, 290, 812 by common division method
• Least Common Multiple of 420, 290, 812 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 5 x 7 x 29 x 3 x 1 x 1 = 12180

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 420,290,812 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(420,290,812) = 2

common factors(in case of two or more numbers have common factors) = 4060

GCF(420,290,812) x common factors =2 x 4060 = 8120

LCM(420,290,812) = ( 420 × 290 × 812 ) / 8120

LCM(420,290,812) = 98901600 / 8120

LCM(420,290,812) = 12180

∴ Least Common Multiple of 420,290,812 is 12180

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

• LCM of 984, 143, 432
• LCM of 353, 481, 288
