The LCM of smallest two digits composite number and the smallest composite number is​?


Question: The LCM of smallest two digits composite number and the smallest composite number is​.....

The composite numbers are the whole numbers that have more than two factors, unlike prime numbers.

Answer:  LCM of the smallest two digit composite number and the smallest composite number is​ 20

Let's find the LCM of smallest two digit composite number and the smallest composite number

Explanation:

The smallest two digit composite number is 10 .The divisors of 10 are 1,2,5,10.

The smallest composite number is 4. The divisors of 4 are 1,2,4. 

Let's find their LCM by Prime Factorization

4= 1 × 2 ×  2

10= 1 ×  2 ×  5

LCM = 2 ×  2 ×  5 = 20

Therfore, LCM of the smallest two digit composite number and the smallest composite number is 20.
