Least Common Multiple of 56, 56, 43, 21

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

• Least Common Multiple of 56, 56, 43, 21 by common division method
• Least Common Multiple of 56, 56, 43, 21 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 2 x 7 x 1 x 1 x 43 x 3 = 7224

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 56,56,43,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(56,56,43,21) = 1

common factors(in case of two or more numbers have common factors) = 392

GCF(56,56,43,21) x common factors =1 x 392 = 392

LCM(56,56,43,21) = ( 56 × 56 × 43 × 21 ) / 392

LCM(56,56,43,21) = 2831808 / 392

LCM(56,56,43,21) = 7224

∴ Least Common Multiple of 56,56,43,21 is 7224

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