Least Common Multiple of 289, 1981

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

• Least Common Multiple of 289, 1981 by common division method
• Least Common Multiple of 289, 1981 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 572509

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 289,1981 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(289,1981) = 1

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

GCF(289,1981) x common factors =1 x 1 = 1

LCM(289,1981) = ( 289 × 1981 ) / 1

LCM(289,1981) = 572509 / 1

LCM(289,1981) = 572509

∴ Least Common Multiple of 289,1981 is 572509

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

• LCM of 433, 8811
• LCM of 282, 8875
• LCM of 291, 4470
• LCM of 534, 9368
• LCM of 395, 3936
