Least Common Multiple of 84, 61, 20, 61

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

• Least Common Multiple of 84, 61, 20, 61 by common division method
• Least Common Multiple of 84, 61, 20, 61 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 61 x 21 x 1 x 5 x 1 = 25620

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 84,61,20,61 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(84,61,20,61) = 1

common factors(in case of two or more numbers have common factors) = 244

GCF(84,61,20,61) x common factors =1 x 244 = 244

LCM(84,61,20,61) = ( 84 × 61 × 20 × 61 ) / 244

LCM(84,61,20,61) = 6251280 / 244

LCM(84,61,20,61) = 25620

∴ Least Common Multiple of 84,61,20,61 is 25620

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