Step-by-step explanation:
A prime number is a number greater than 1 with only two factors – themselves and 1.
A prime number cannot be divided by any other numbers without leaving a remainder.
An example of a prime number is 13. It can only be divided by 1 and 13. Dividing a prime number by another number results in numbers left over e.g. 13 ÷ 6 = 2 remainder 1.
15 is not an example of a prime number because it can be divided by 5 and 3 as well as by itself and 1.
15 is an example of a composite number because it has more than two factors.
Ex- 2,3,5,7,11
