Least Common Multiple of 642, 2009

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

• Least Common Multiple of 642, 2009 by common division method
• Least Common Multiple of 642, 2009 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 1289778

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 642,2009 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(642,2009) = 1

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

GCF(642,2009) x common factors =1 x 1 = 1

LCM(642,2009) = ( 642 × 2009 ) / 1

LCM(642,2009) = 1289778 / 1

LCM(642,2009) = 1289778

∴ Least Common Multiple of 642,2009 is 1289778

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

• LCM of 187, 6374
• LCM of 566, 2438
• LCM of 162, 9846
• LCM of 521, 7267
• LCM of 403, 9459
