Least Common Multiple of 391, 646, 989

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

• Least Common Multiple of 391, 646, 989 by common division method
• Least Common Multiple of 391, 646, 989 with GCF Formula

∴ So the LCM of the given numbers is 17 x 23 x 1 x 38 x 43 = 638894

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 391,646,989 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(391,646,989) = 1

common factors(in case of two or more numbers have common factors) = 391

GCF(391,646,989) x common factors =1 x 391 = 391

LCM(391,646,989) = ( 391 × 646 × 989 ) / 391

LCM(391,646,989) = 249807554 / 391

LCM(391,646,989) = 638894

∴ Least Common Multiple of 391,646,989 is 638894
