Least Common Multiple of 57, 68, 57, 42

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

• Least Common Multiple of 57, 68, 57, 42 by common division method
• Least Common Multiple of 57, 68, 57, 42 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 19 x 1 x 34 x 1 x 7 = 27132

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 57,68,57,42 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(57,68,57,42) = 1

common factors(in case of two or more numbers have common factors) = 342

GCF(57,68,57,42) x common factors =1 x 342 = 342

LCM(57,68,57,42) = ( 57 × 68 × 57 × 42 ) / 342

LCM(57,68,57,42) = 9279144 / 342

LCM(57,68,57,42) = 27132

∴ Least Common Multiple of 57,68,57,42 is 27132
