LCM(81, 615) = 16605
LCM of 81, 615
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 81, 615 by common division method
- Least Common Multiple of 81, 615 with GCF Formula
Least Common Multiple (LCM) of 81,615 is 16605
| 3 | 81, 615 |
| 27, 205 |
∴ So the LCM of the given numbers is 3 x 27 x 205 = 16605
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 81,615 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,615) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(81,615) x common factors =3 x 1 = 3
LCM(81,615) = ( 81 × 615 ) / 3
LCM(81,615) = 49815 / 3
LCM(81,615) = 16605
∴ Least Common Multiple of 81,615 is 16605
