Least Common Multiple of 31, 68, 8

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

• Least Common Multiple of 31, 68, 8 by common division method
• Least Common Multiple of 31, 68, 8 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 31 x 17 x 2 = 4216

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 31,68,8 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(31,68,8) = 1

common factors(in case of two or more numbers have common factors) = 4

GCF(31,68,8) x common factors =1 x 4 = 4

LCM(31,68,8) = ( 31 × 68 × 8 ) / 4

LCM(31,68,8) = 16864 / 4

LCM(31,68,8) = 4216

∴ Least Common Multiple of 31,68,8 is 4216

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

• LCM of 49, 38, 7
• LCM of 55, 91, 7
• LCM of 36, 40, 9
• LCM of 33, 59, 2
• LCM of 12, 70, 2
