Least Common Multiple of 13, 31, 87, 861

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

• Least Common Multiple of 13, 31, 87, 861 by common division method
• Least Common Multiple of 13, 31, 87, 861 with GCF Formula

∴ So the LCM of the given numbers is 3 x 13 x 31 x 29 x 287 = 10062507

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 13,31,87,861 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(13,31,87,861) = 1

common factors(in case of two or more numbers have common factors) = 3

GCF(13,31,87,861) x common factors =1 x 3 = 3

LCM(13,31,87,861) = ( 13 × 31 × 87 × 861 ) / 3

LCM(13,31,87,861) = 30187521 / 3

LCM(13,31,87,861) = 10062507

∴ Least Common Multiple of 13,31,87,861 is 10062507
