Least Common Multiple of 36, 20, 86, 90

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

• Least Common Multiple of 36, 20, 86, 90 by common division method
• Least Common Multiple of 36, 20, 86, 90 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 5 x 1 x 1 x 43 x 1 = 7740

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 36,20,86,90 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(36,20,86,90) = 2

common factors(in case of two or more numbers have common factors) = 360

GCF(36,20,86,90) x common factors =2 x 360 = 720

LCM(36,20,86,90) = ( 36 × 20 × 86 × 90 ) / 720

LCM(36,20,86,90) = 5572800 / 720

LCM(36,20,86,90) = 7740

∴ Least Common Multiple of 36,20,86,90 is 7740

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