Least Common Multiple of 68, 28, 408

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

• Least Common Multiple of 68, 28, 408 by common division method
• Least Common Multiple of 68, 28, 408 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 17 x 1 x 7 x 6 = 2856

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 68,28,408 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(68,28,408) = 4

common factors(in case of two or more numbers have common factors) = 68

GCF(68,28,408) x common factors =4 x 68 = 272

LCM(68,28,408) = ( 68 × 28 × 408 ) / 272

LCM(68,28,408) = 776832 / 272

LCM(68,28,408) = 2856

∴ Least Common Multiple of 68,28,408 is 2856

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