Least Common Multiple of 23, 31, 687

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

• Least Common Multiple of 23, 31, 687 by common division method
• Least Common Multiple of 23, 31, 687 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 489831

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 23,31,687 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(23,31,687) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(23,31,687) x common factors =1 x 1 = 1

LCM(23,31,687) = ( 23 × 31 × 687 ) / 1

LCM(23,31,687) = 489831 / 1

LCM(23,31,687) = 489831

∴ Least Common Multiple of 23,31,687 is 489831

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

• LCM of 13, 98, 746
• LCM of 19, 97, 822
• LCM of 33, 37, 563
• LCM of 32, 57, 194
• LCM of 59, 38, 417
