Least Common Multiple of 23, 31, 21, 644

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

• Least Common Multiple of 23, 31, 21, 644 by common division method
• Least Common Multiple of 23, 31, 21, 644 with GCF Formula

∴ So the LCM of the given numbers is 7 x 23 x 1 x 31 x 3 x 4 = 59892

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 23,31,21,644 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(23,31,21,644) = 1

common factors(in case of two or more numbers have common factors) = 161

GCF(23,31,21,644) x common factors =1 x 161 = 161

LCM(23,31,21,644) = ( 23 × 31 × 21 × 644 ) / 161

LCM(23,31,21,644) = 9642612 / 161

LCM(23,31,21,644) = 59892

∴ Least Common Multiple of 23,31,21,644 is 59892
