# Prime Or Composite ? How Can We Find Meaning Of Number ? In mathematics, a prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. A composite number is a natural number that can be formed by multiplying two smaller natural numbers. Prime numbers have many interesting properties. For example, the sum of any two prime numbers is also a prime number. This is not true for composite numbers. The product of any two composite numbers is also a composite number.

To check if a number is prime or composite, you can use the following algorithm:

• Iterate through a range of numbers from 2 to the square root of the number you are checking.
• For each number in the range, check if the number you are checking is divisible by it.
• If the number is divisible by any number in the range, it is a composite number.
• If the number is not divisible by any number in the range, it is a prime number.Can a number transform as prime or composite ?

No, a number cannot change from being prime to composite or vice versa. A prime number is a positive integer greater than 1 that is divisible by only 1 and itself, and a composite number is a positive integer greater than 1 that is divisible by at least one positive integer other than 1 and itself. Once a number is determined to be either prime or composite, it will always be that way.

## Do Prime numbers divide Prime number ?

Prime numbers can divide other numbers, including other prime numbers. However, when a prime number divides another prime number, the result is always a composite number.

For example, if we take the prime number 3 and divide it by another prime number, say 5, we get the result of 0.75 (3/5) which is a decimal number, not an integer. Therefore 5 is not a divisor of 3.

In summary, prime numbers can divide other numbers, including other prime numbers, but the result will always be a composite number (unless the divisor is 1).
