Integers Prime Numbers

In math, the whole numbers are called as integers. Likewise, the prime numbers are always integers that are whole numbers. It does not contain any sign in front of the number. It is also called as natural numbers. Now we are going to see about prime numbers are integers.
Explanation for Integers Prime Numbers

Some notes about prime numbers in math:

A number which has only two distinct divisors is called as prime numbers that is indicated as integers. The property primality is included in prime numbers. In two distinct divisors, 1 is constant divisor of all prime numbers. The prime number’s factor series is n = p1, p2,……pt.

Determine the prime numbers in math:

Step 1: The multiple factors of number are listed.

Step 2: State the given number is prime number when it has two divisors. If there are more than two divisors, we can call that number is composite number.

If we take the number as greater than 100 means, how we find whether that number is prime or not. Do the following procedures.

Procedure 1: Find out the square root of number.

Procedure 2: List the prime numbers of rounded value.

Procedure 3: Find out whether the listed prime numbers are divide the rounded value or not.

Procedure 4: If the listed prime numbers are not divide the given number means that is called as prime number.

Example problems for integers prime numbers:

Problem 1: State the given integer is prime or not.

134

Answer:

Given integer are 134.

Square root value of 134 is 11.57.

The square root value is rounded as 12.

List the below 12 prime numbers are 2, 3, 5, 7, 11.

In above prime numbers, the integer 2 is dividing the 134.

Finally, the given integer 134 is not a prime number.

Problem 2: Find out which is not a prime number from the below list.

31, 43, 53, 29, 23, 60

Answer:

The number is 60 is not a prime number. Because it has factors more than two.
