Least Common Multiple of 643, 989

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

• Least Common Multiple of 643, 989 by common division method
• Least Common Multiple of 643, 989 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 635927

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 643,989 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(643,989) = 1

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

GCF(643,989) x common factors =1 x 1 = 1

LCM(643,989) = ( 643 × 989 ) / 1

LCM(643,989) = 635927 / 1

LCM(643,989) = 635927

∴ Least Common Multiple of 643,989 is 635927

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

• LCM of 717, 915
• LCM of 626, 421
• LCM of 448, 399
• LCM of 923, 808
