Least Common Multiple of 31, 31, 21, 649

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

• Least Common Multiple of 31, 31, 21, 649 by common division method
• Least Common Multiple of 31, 31, 21, 649 with GCF Formula

∴ So the LCM of the given numbers is 31 x 1 x 1 x 21 x 649 = 422499

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 31,31,21,649 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(31,31,21,649) = 1

common factors(in case of two or more numbers have common factors) = 31

GCF(31,31,21,649) x common factors =1 x 31 = 31

LCM(31,31,21,649) = ( 31 × 31 × 21 × 649 ) / 31

LCM(31,31,21,649) = 13097469 / 31

LCM(31,31,21,649) = 422499

∴ Least Common Multiple of 31,31,21,649 is 422499
