Prime Numbers
A prime number is the one which has exactly two factors, which means, it can be divided by only “1” and itself. But “1” is not a prime number.
Example of Prime Number
3 is a prime number because 3 can be divided by only two number’s i.e. 1 and 3 itself.
3/1 = 3
3/3 = 1
In the same way, 2, 5, 7, 11, 13, 17 are prime numbers.
Composite Numbers
A composite number has more than two factors, which means apart from getting divided by number 1 and itself, it can also be divided by at least one integer or number. We don’t consider ‘1’ as a composite number.
Example of Composite Number
12 is a composite number because it can be divided by 1,2,3,4,6 and 12. So, the number ‘12’ has 6 factors.
12/1 = 12
12/2 =6
12/3 =4
12/4 =3
12/6 =2
12/12 =1
