Least Common Multiple of 644, 123

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

• Least Common Multiple of 644, 123 by common division method
• Least Common Multiple of 644, 123 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 79212

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 644,123 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(644,123) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(644,123) x common factors =1 x 1 = 1

LCM(644,123) = ( 644 × 123 ) / 1

LCM(644,123) = 79212 / 1

LCM(644,123) = 79212

∴ Least Common Multiple of 644,123 is 79212

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 618, 266
• LCM of 975, 531
• LCM of 389, 706
• LCM of 408, 552
• LCM of 429, 184
