**Prime and Composite Numbers**

We are now familiar with the factors of a number. Observe the number of factors

of a few numbers arranged in this table.

We find that

(a) The number 1 has only one factor (i.e. itself ).

(b) There are numbers, having exactly two factors 1 and the number itself. Such

number are 2, 3, 5, 7, 11 etc. These numbers are prime numbers.

The numbers other than 1 whose only factors are 1 and the number itself

are called Prime numbers.

Try to find some more prime numbers other than these.

(c) There are numbers having more than two factors like 4, 6, 8, 9, 10 and so on.

These numbers are composite numbers.

Numbers having more than two factors are

called Composite numbers.

Is 15 a composite number? Why? What about

18? 25?

**Even and Odd numbers**

Do you observe any pattern in the numbers 2, 4, 6, 8, 10, 12, 14, …? You will

find that each of them is a multiple of 2.

These are called even numbers. The rest of the numbers 1, 3, 5, 7, 9, 11,…

are called odd numbers.

You can verify that a two-digit number or a three-digit number is even or not.

How will you know whether a number like 756482 is even? By dividing it by 2.

Will it not be tedious?

We say that a number with 0, 2, 4, 6, 8 at the ones place is an even number.

So, 350, 4862, 59246 are even numbers. The numbers 457, 2359, 8231 are all

odd. Let us try to find some interesting facts:

(a) Which is the smallest even number? It is 2. Which is the smallest prime

number? It is again 2.

Thus, 2 is the smallest prime number which is even.

(b) The other prime numbers are 3, 5, 7, 11, 13, … . Do you find any even number

in this list? Of course not, they are all odd.

Thus, we can say that every prime number except 2 is odd.
