Is 1369 a prime number?

The number 1369 has got multiple factors, that are capable of dividing the number completely without leaving any remainder. Thus the number 1369 is a non-prime number. The factors of 1369 include 1, 37, 41, and 1369.

A number to be a prime number should follow the criteria, which is that it should not have factors more than 2. Here, 1369 has more than 2 factors, hence making it a composite number.

Given below are a few ways that can be used to find prime or composite numbers.

The different methods we can use to check if a number is a prime number are explained below:

1. Counting Divisors Method
2. Divisibility Test
3. Prime Number Chart
4. Prime Factorization

For the counting divisors method, it is to be checked whether the number is divisible by any numbers other than 1 and the number itself.

The counting divisors method for 1369 would simply be:

Divisors of 1369 = 1, 37, 41, 1369
Number of divisors = 4

The number 1369 can be considered composite.

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, the prime number only has 2 divisors, which are 1 and itself.

The divisors of 1369 are 1, 37, 41, and 1369.

Thus, 1369 consists of 4 factors that divide it completely without any remainder.

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

The list of prime numbers under 100 are:
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

1369 is not a prime number since it is divisible by numbers other than 1 and itself.

This method is only used for a non-prime number/composite number. Since 1369 is a composite number, the prime factorization for 1369 is:

Factors of 1369 = 37 × 41
 

Prime Number: A natural number greater than 1 that has exactly two distinct positive divisors: 1 and itself. For example, 2, 3, and 5 are prime numbers.

Composite Number: A natural number greater than 1 that has more than two divisors. For instance, 1369 is composite because it has divisors other than 1 and itself, such as 37 and 41.

Divisors: Numbers that divide another number exactly without leaving a remainder. For example, the divisors of 1369 are 1, 37, 41, and 1369.

Prime Factorization: The expression of a number as a product of its prime factors. For example, the prime factorization of 1369 is 37 × 41.

Divisibility Test: A method used to determine whether a number is divisible by another number. If the number divides evenly, it is considered divisible, and if it leaves a remainder, it is not divisible.
