Least Common Multiple of 99, 55, 20, 60

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

• Least Common Multiple of 99, 55, 20, 60 by common division method
• Least Common Multiple of 99, 55, 20, 60 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 11 x 3 x 1 x 1 x 1 = 1980

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 99,55,20,60 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(99,55,20,60) = 1

common factors(in case of two or more numbers have common factors) = 3300

GCF(99,55,20,60) x common factors =1 x 3300 = 3300

LCM(99,55,20,60) = ( 99 × 55 × 20 × 60 ) / 3300

LCM(99,55,20,60) = 6534000 / 3300

LCM(99,55,20,60) = 1980

∴ Least Common Multiple of 99,55,20,60 is 1980

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