Least Common Multiple of 645, 430, 998

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

• Least Common Multiple of 645, 430, 998 by common division method
• Least Common Multiple of 645, 430, 998 with GCF Formula

∴ So the LCM of the given numbers is 2 x 5 x 43 x 3 x 1 x 499 = 643710

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 645,430,998 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(645,430,998) = 1

common factors(in case of two or more numbers have common factors) = 430

GCF(645,430,998) x common factors =1 x 430 = 430

LCM(645,430,998) = ( 645 × 430 × 998 ) / 430

LCM(645,430,998) = 276795300 / 430

LCM(645,430,998) = 643710

∴ Least Common Multiple of 645,430,998 is 643710
