Using the Divisibility Method

In the division test, we try to divide the number by any of the prime numbers. If we cannot, then it is considered a prime number.


In the divisibility method, a prime number only has 2 divisors, which are 1 and itself.


The divisors of 1433 are 1 and 1433.


Thus, 1433 consists of 2 factors that divide it completely without any remainder, confirming it is a prime number.

Using the Prime Number Chart

The prime number chart is the list of prime numbers starting from 2 to infinity.


The list of prime numbers from 1400 to 1500 are:


1409, 1423, 1427, 1429, 1433, 1439, 1447, 1451, 1453, 1459, 1471, 1481, 1483, 1487, 1489, 1493


1433 is present in this list, confirming it is a prime number.

Using the Prime Factorization

This method is only used for a non-prime number/composite number. Since 1433 is a prime number, it does not have a prime factorization other than 1×1433.
