Least Common Multiple of 71, 63, 639

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

• Least Common Multiple of 71, 63, 639 by common division method
• Least Common Multiple of 71, 63, 639 with GCF Formula

∴ So the LCM of the given numbers is 3 x 3 x 71 x 1 x 7 x 1 = 4473

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 71,63,639 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(71,63,639) = 1

common factors(in case of two or more numbers have common factors) = 639

GCF(71,63,639) x common factors =1 x 639 = 639

LCM(71,63,639) = ( 71 × 63 × 639 ) / 639

LCM(71,63,639) = 2858247 / 639

LCM(71,63,639) = 4473

∴ Least Common Multiple of 71,63,639 is 4473

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

• LCM of 99, 44, 499
• LCM of 64, 22, 366
