Least Common Multiple of 61, 61, 35, 20

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

• Least Common Multiple of 61, 61, 35, 20 by common division method
• Least Common Multiple of 61, 61, 35, 20 with GCF Formula

∴ So the LCM of the given numbers is 5 x 61 x 1 x 1 x 7 x 4 = 8540

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 61,61,35,20 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(61,61,35,20) = 1

common factors(in case of two or more numbers have common factors) = 305

GCF(61,61,35,20) x common factors =1 x 305 = 305

LCM(61,61,35,20) = ( 61 × 61 × 35 × 20 ) / 305

LCM(61,61,35,20) = 2604700 / 305

LCM(61,61,35,20) = 8540

∴ Least Common Multiple of 61,61,35,20 is 8540

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