Least Common Multiple of 645, 817, 39

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

• Least Common Multiple of 645, 817, 39 by common division method
• Least Common Multiple of 645, 817, 39 with GCF Formula

∴ So the LCM of the given numbers is 3 x 43 x 5 x 19 x 13 = 159315

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 645,817,39 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(645,817,39) = 1

common factors(in case of two or more numbers have common factors) = 129

GCF(645,817,39) x common factors =1 x 129 = 129

LCM(645,817,39) = ( 645 × 817 × 39 ) / 129

LCM(645,817,39) = 20551635 / 129

LCM(645,817,39) = 159315

∴ Least Common Multiple of 645,817,39 is 159315

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

• LCM of 144, 143, 41
• LCM of 424, 251, 80
