Least Common Multiple of 639, 279, 217

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

• Least Common Multiple of 639, 279, 217 by common division method
• Least Common Multiple of 639, 279, 217 with GCF Formula

∴ So the LCM of the given numbers is 3 x 3 x 31 x 71 x 1 x 7 = 138663

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 639,279,217 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(639,279,217) = 1

common factors(in case of two or more numbers have common factors) = 279

GCF(639,279,217) x common factors =1 x 279 = 279

LCM(639,279,217) = ( 639 × 279 × 217 ) / 279

LCM(639,279,217) = 38686977 / 279

LCM(639,279,217) = 138663

∴ Least Common Multiple of 639,279,217 is 138663

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