Least Common Multiple of 642, 1855

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

• Least Common Multiple of 642, 1855 by common division method
• Least Common Multiple of 642, 1855 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 1190910

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 642,1855 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(642,1855) = 1

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

GCF(642,1855) x common factors =1 x 1 = 1

LCM(642,1855) = ( 642 × 1855 ) / 1

LCM(642,1855) = 1190910 / 1

LCM(642,1855) = 1190910

∴ Least Common Multiple of 642,1855 is 1190910

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

• LCM of 220, 4372
• LCM of 306, 2802
• LCM of 650, 1392
• LCM of 647, 1478
• LCM of 723, 6809
