Least Common Multiple of 72, 40, 636

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

• Least Common Multiple of 72, 40, 636 by common division method
• Least Common Multiple of 72, 40, 636 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 3 x 5 x 53 = 19080

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 72,40,636 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(72,40,636) = 4

common factors(in case of two or more numbers have common factors) = 24

GCF(72,40,636) x common factors =4 x 24 = 96

LCM(72,40,636) = ( 72 × 40 × 636 ) / 96

LCM(72,40,636) = 1831680 / 96

LCM(72,40,636) = 19080

∴ Least Common Multiple of 72,40,636 is 19080

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

• LCM of 65, 92, 438
• LCM of 27, 59, 142
• LCM of 89, 85, 872
• LCM of 82, 45, 369
• LCM of 26, 14, 927
