Question

Write down the numbers with more than 2 different factors

Answer 1

Step-by-step explanation:

The prime numbers less than

20

are

2

,

3

,

5

,

7

,

11

,

13

,

17

,

and

19

. There are many larger prime numbers too. In order to determine whether a number is prime or composite, we need to see if the number has any factors other than

1

and itself. To do this, we can test each of the smaller prime numbers in order to see if it is a factor of the number. If none of the prime numbers are factors, then that number is also prime.
