Least Common Multiple of 645, 555

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

• Least Common Multiple of 645, 555 by common division method
• Least Common Multiple of 645, 555 with GCF Formula

∴ So the LCM of the given numbers is 3 x 5 x 43 x 37 = 23865

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 645,555 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(645,555) = 15

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

GCF(645,555) x common factors =15 x 1 = 15

LCM(645,555) = ( 645 × 555 ) / 15

LCM(645,555) = 357975 / 15

LCM(645,555) = 23865

∴ Least Common Multiple of 645,555 is 23865

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

• LCM of 983, 347
• LCM of 911, 478
• LCM of 994, 946
• LCM of 881, 893
