Least Common Multiple of 31, 57, 561

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

• Least Common Multiple of 31, 57, 561 by common division method
• Least Common Multiple of 31, 57, 561 with GCF Formula

∴ So the LCM of the given numbers is 3 x 31 x 19 x 187 = 330429

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 31,57,561 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(31,57,561) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(31,57,561) x common factors =1 x 3 = 3

LCM(31,57,561) = ( 31 × 57 × 561 ) / 3

LCM(31,57,561) = 991287 / 3

LCM(31,57,561) = 330429

∴ Least Common Multiple of 31,57,561 is 330429

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