Least Common Multiple of 71, 31, 643

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

• Least Common Multiple of 71, 31, 643 by common division method
• Least Common Multiple of 71, 31, 643 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 1415243

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 71,31,643 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(71,31,643) = 1

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

GCF(71,31,643) x common factors =1 x 1 = 1

LCM(71,31,643) = ( 71 × 31 × 643 ) / 1

LCM(71,31,643) = 1415243 / 1

LCM(71,31,643) = 1415243

∴ Least Common Multiple of 71,31,643 is 1415243

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

• LCM of 78, 84, 903
• LCM of 86, 95, 109
• LCM of 47, 24, 770
• LCM of 22, 79, 111
