Least common multiple (LCM) of 15, 13, 821 is 160095.

LCM(15, 13, 821) = 160095

LCM of 15, 13, 821

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

LCM of:

Least Common Multiple of 15,13,821

Least Common Multiple (LCM) of 15,13,821 is 160095

Given numbers has no common factors except 1. So, there LCM is their product i.e 160095

Least Common Multiple of 15,13,821 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 15,13,821 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(15,13,821) = 1

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

GCF(15,13,821) x common factors =1 x 1 = 1

LCM(15,13,821) = ( 15 × 13 × 821 ) / 1

LCM(15,13,821) = 160095 / 1

LCM(15,13,821) = 160095

∴ Least Common Multiple of 15,13,821 is 160095
