Least Common Multiple of 70, 35, 18, 72

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

• Least Common Multiple of 70, 35, 18, 72 by common division method
• Least Common Multiple of 70, 35, 18, 72 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 7 x 1 x 1 x 1 x 4 = 2520

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 70,35,18,72 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,35,18,72) = 1

common factors(in case of two or more numbers have common factors) = 1260

GCF(70,35,18,72) x common factors =1 x 1260 = 1260

LCM(70,35,18,72) = ( 70 × 35 × 18 × 72 ) / 1260

LCM(70,35,18,72) = 3175200 / 1260

LCM(70,35,18,72) = 2520

∴ Least Common Multiple of 70,35,18,72 is 2520

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