Least Common Multiple of 20, 57, 798

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

• Least Common Multiple of 20, 57, 798 by common division method
• Least Common Multiple of 20, 57, 798 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 19 x 10 x 1 x 7 = 7980

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 20,57,798 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,57,798) = 1

common factors(in case of two or more numbers have common factors) = 114

GCF(20,57,798) x common factors =1 x 114 = 114

LCM(20,57,798) = ( 20 × 57 × 798 ) / 114

LCM(20,57,798) = 909720 / 114

LCM(20,57,798) = 7980

∴ Least Common Multiple of 20,57,798 is 7980

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