Least Common Multiple of 642, 855, 731

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

• Least Common Multiple of 642, 855, 731 by common division method
• Least Common Multiple of 642, 855, 731 with GCF Formula

∴ So the LCM of the given numbers is 3 x 214 x 285 x 731 = 133751070

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 642,855,731 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(642,855,731) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(642,855,731) x common factors =1 x 3 = 3

LCM(642,855,731) = ( 642 × 855 × 731 ) / 3

LCM(642,855,731) = 401253210 / 3

LCM(642,855,731) = 133751070

∴ Least Common Multiple of 642,855,731 is 133751070
