Least Common Multiple of 645, 140

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

• Least Common Multiple of 645, 140 by common division method
• Least Common Multiple of 645, 140 with GCF Formula

∴ So the LCM of the given numbers is 5 x 129 x 28 = 18060

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 645,140 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(645,140) = 5

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

GCF(645,140) x common factors =5 x 1 = 5

LCM(645,140) = ( 645 × 140 ) / 5

LCM(645,140) = 90300 / 5

LCM(645,140) = 18060

∴ Least Common Multiple of 645,140 is 18060

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

• LCM of 650, 697
• LCM of 819, 400
• LCM of 798, 493
• LCM of 586, 240
• LCM of 283, 863
