Least Common Multiple of 644, 653

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

• Least Common Multiple of 644, 653 by common division method
• Least Common Multiple of 644, 653 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 420532

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 644,653 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(644,653) = 1

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

GCF(644,653) x common factors =1 x 1 = 1

LCM(644,653) = ( 644 × 653 ) / 1

LCM(644,653) = 420532 / 1

LCM(644,653) = 420532

∴ Least Common Multiple of 644,653 is 420532

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

• LCM of 734, 139
• LCM of 534, 230
• LCM of 949, 594
• LCM of 223, 226
• LCM of 396, 874
