## #What are all Prime Numbers?

A prime number is a number that is greater than one having only two factors - 1 and the number itself. In other words, we cannot divide a prime number into equal groups. For example, 3 cannot be split into a group of equal numbers.

### Factorization of 3:

3 × 1 = 3

1 × 3 = 3

As you can see, 3 has only two elements – 1 and 3.

Therefore, 3 is a prime number.

## #Are all Prime Numbers Odd?

Factorization is the most effective method for locating prime numbers. The following steps are involved in utilizing the factorization method:

• To begin, determine the components of the given integer.
• Determine the number of components that make up that amount.
• If there are more than two components, the number is not a prime number.

For example:

2, 3, 5, 7, 11, 19, 37, 41, 83, 313 etc.

2 = 1 × 2

3 = 1 × 3

13 = 1 × 13 and etc.

As a result, all of the preceding numbers have precisely two components, namely 1 and the number itself. As a result, they are all prime numbers.

## #Prime and Composite Numbers

A Prime Number is a natural number that contains precisely two components, namely 1 and the number itself. In other terms, a prime number can only be divided by one and itself.

Let us use the number 17 as an example.

1 x 17 is the prime factorization of 17. As you can see, there are two factors of 17. As a result, it is a prime number.

A Composite Number is any non-prime number.

Composite numbers are natural numbers that have more than two components. Such numbers are also divisible by other numbers.

Let us use the number 35 as an example.

35 can now be written as 5 × 7 × 7. So the factors of 35 are 1, 5, 7, and 35. Because 35 has more than two components, it is not a prime number but a composite number.
