Given : The numbers are :

1. Smallest prime number.
2. Smallest odd composite number.

To find : The LCM of the said numbers.

Solution :

We can simply solve this mathematical problem by using the following mathematical process.

Now,

The smallest prime number = 2

The smallest odd composite number = 9

Their LCM (Lowest common multiple) will be :

2 | 2,9

____

9 | 1,9

____

ㅤㅤ1,1

LCM (Lowest common multiple) of the said numbers = 2×9 = 18

(This will be considered as the final result.)

Hence, the LCM will be 18
