Least Common Multiple of 644, 782, 42

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

• Least Common Multiple of 644, 782, 42 by common division method
• Least Common Multiple of 644, 782, 42 with GCF Formula

∴ So the LCM of the given numbers is 2 x 7 x 23 x 2 x 17 x 3 = 32844

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 644,782,42 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(644,782,42) = 2

common factors(in case of two or more numbers have common factors) = 322

GCF(644,782,42) x common factors =2 x 322 = 644

LCM(644,782,42) = ( 644 × 782 × 42 ) / 644

LCM(644,782,42) = 21151536 / 644

LCM(644,782,42) = 32844

∴ Least Common Multiple of 644,782,42 is 32844

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

• LCM of 266, 495, 34
• LCM of 150, 707, 96
• LCM of 950, 224, 22
