Least Common Multiple of 1981, 4221

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

• Least Common Multiple of 1981, 4221 by common division method
• Least Common Multiple of 1981, 4221 with GCF Formula

∴ So the LCM of the given numbers is 7 x 283 x 603 = 1194543

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 1981,4221 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1981,4221) = 7

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

GCF(1981,4221) x common factors =7 x 1 = 7

LCM(1981,4221) = ( 1981 × 4221 ) / 7

LCM(1981,4221) = 8361801 / 7

LCM(1981,4221) = 1194543

∴ Least Common Multiple of 1981,4221 is 1194543

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

• LCM of 2790, 1807
