Least Common Multiple of 20, 810, 270

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

• Least Common Multiple of 20, 810, 270 by common division method
• Least Common Multiple of 20, 810, 270 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 3 x 3 x 5 x 2 x 1 x 3 = 1620

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 20,810,270 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,810,270) = 10

common factors(in case of two or more numbers have common factors) = 270

GCF(20,810,270) x common factors =10 x 270 = 2700

LCM(20,810,270) = ( 20 × 810 × 270 ) / 2700

LCM(20,810,270) = 4374000 / 2700

LCM(20,810,270) = 1620

∴ Least Common Multiple of 20,810,270 is 1620

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

• LCM of 54, 731, 569
• LCM of 62, 220, 670
