Is 36 a prime number?

To check a number 36 is a prime number or composite, you need to divide it with numbers from 1 to 36. The number 36 holds more than two factors, so it is said to be a composite number.

Why is 36 not a prime number?

Thirty-six cannot be a prime number, where it is divisible by numbers like 1, 2, 3,4, 6, 9, 12, 18, and 36. Where the prime numbers should only be divisible by 1 and themselves. Thirty-six has more divisors, it does not meet the prime number definition.

Using the Counting Divisors Method

By using the counting divisors method, children can easily find out the divisors of a number. 

 

List the divisors of 36 -  1, 2, 3, 4, 6, 9, 12, 18, and 36.

 

Count the number of divisors - 9

 

Then, the number 36 is a composite number

Using the Divisibility Test Method

In this method, we list the divisors of a number and check the given number is prime or composite.

 

The divisors of 36 will be: 1, 2, 3, 4, 6, 9, 12, 18, and 36.

 

Where thirty-six has more than two divisors, then the number will be a prime.

Using Prime Number Chart

The prime numbers up to 36 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, and 31.

 

This chart helps to quickly identify the distribution of prime numbers within this range and clearly shows that 36 is not among them.

Using the Prime Factorization Method

This method is especially used for a non-prime or composite number. To find the prime factorization, the number should be divided into small prime numbers.

 

Step 1: Start with 36 at first.


Step 2: 36 is divided into 2 (prime) and 18.


Step 3: 18 is then divided into 2 (prime) and 9.


Step 4: 9 is divided into 3 and 3 (prime)

 

The prime factors are: 2 (twice) and 3 (twice).

 

Therefore, the prime factorization of 36 = 2×2×3×3
