Question

Find the lcm of smallest prime number and smallest odd composite natural number

Answer 1

Answer:

The smallest prime number is 2 and smallest odd composite number is 9.

Step-by-step explanation:

the L.C.M for 2,9 = 2x9 =18.

Answer 2

The lcm of smallest prime number and smallest odd composite natural number is 18 .

Explanation:

• Prime number = A number that has only two factors (1 and the number itself) . For ex: 2 ,3 ,5 , 7...
• Composite numbers = A number that has more than two factor. For ex: 4 , 6 ,8 ,9, ...
• Least common multiple of two numbers is the smallest number that is divisible by both numbers.

We know that the smallest prime number =2

The smallest odd composite number =9

Since both are co-primes ( both have no common factor).

The least common multiple(lcm) of 2 and 9 = $2\times9=18$

Hence, the lcm of smallest prime number and smallest odd composite natural number = 18
