Least Common Multiple of 840, 489

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

• Least Common Multiple of 840, 489 by common division method
• Least Common Multiple of 840, 489 with GCF Formula

∴ So the LCM of the given numbers is 3 x 280 x 163 = 136920

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 840,489 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(840,489) = 3

common factors(in case of two or more numbers have common factors) = 1

GCF(840,489) x common factors =3 x 1 = 3

LCM(840,489) = ( 840 × 489 ) / 3

LCM(840,489) = 410760 / 3

LCM(840,489) = 136920

∴ Least Common Multiple of 840,489 is 136920

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

• LCM of 467, 790
• LCM of 547, 743
• LCM of 238, 655
• LCM of 725, 116
