Least Common Multiple of 10, 55, 56, 20

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

• Least Common Multiple of 10, 55, 56, 20 by common division method
• Least Common Multiple of 10, 55, 56, 20 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 5 x 1 x 11 x 14 x 1 = 3080

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 10,55,56,20 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(10,55,56,20) = 1

common factors(in case of two or more numbers have common factors) = 200

GCF(10,55,56,20) x common factors =1 x 200 = 200

LCM(10,55,56,20) = ( 10 × 55 × 56 × 20 ) / 200

LCM(10,55,56,20) = 616000 / 200

LCM(10,55,56,20) = 3080

∴ Least Common Multiple of 10,55,56,20 is 3080

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