Is 533 a Prime Number

To find the number 533 prime or composite numbers. We need to check the number which holds only two factors, 1 and the number itself. The factors of 533 are 1, 13, 41, and 533, then it becomes the composite number.
 

If you want to conclude the number is prime or composite, check the divisibility of the number. If the number has two factors, then it is a prime number.

There are different methods to follow, some easy methods to find square roots are given below.

• Counting Divisors Method

• Divisibility Test Method

• Prime Number Chart

• Prime Factorization Method

In this counting divisor method, we need to count the divisors of a number. The number, which holds more than two factors, is said to be a composite number.

Let’s check the number 533.

The divisors of 533 = 1, 13, 41, and 533.

533, holds only two divisors, so it is a composite number.
 

For divisibility rule, the number is greater than 1 and can be divisible by 1 and the number itself. In other words, it can be said that if a prime number is divisible by any number, the quotient is not a whole number. 533 is divisible by 1, 13, 41, and 533, therefore, it is a composite number.
 

In this method, we find the square root by listing the prime number chart:

Here, we list the prime numbers up to 550 = 2, 3, 5…521, 523 541.

From the above number chart, we obtained that 533 is a composite number.
 

In this method, we need to find the prime factorization of 533

The prime factorization is said to be the numbers as the product of their prime factors.

Prime factorization of 533 = 13 × 41

Therefore, 533 is factored into smaller prime factors.

• Perfect Divisor: The Integers which are divided into numbers completely without leaving any remainder.

• Composite Number: These numbers hold factors more than itself and one.

• Prime number chart: It consists of all prime numbers from smallest to largest.

• Prime Factorization: It is a number as the product of its prime factors.
