Least Common Multiple of 78, 84, 24, 56

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

• Least Common Multiple of 78, 84, 24, 56 by common division method
• Least Common Multiple of 78, 84, 24, 56 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 7 x 13 x 1 x 1 x 1 = 2184

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 78,84,24,56 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,84,24,56) = 2

common factors(in case of two or more numbers have common factors) = 2016

GCF(78,84,24,56) x common factors =2 x 2016 = 4032

LCM(78,84,24,56) = ( 78 × 84 × 24 × 56 ) / 4032

LCM(78,84,24,56) = 8805888 / 4032

LCM(78,84,24,56) = 2184

∴ Least Common Multiple of 78,84,24,56 is 2184

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