Why is 1237, or not, a prime number?

A number to be a prime number should follow the criteria, which is that it should not have factors more than 2. If 1237 has more than 2 factors, it is 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.

Using the Counting Divisors Method

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 1237 would simply be: Divisors of 1237 = 1, 1237 (since 1237 only has 2 divisors). Number of divisors = 2 Thus, the number 1237 can be considered a prime number.

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, the prime number only has 2 divisors, which are 1 and itself. The divisors of 1237 are 1 and 1237. Thus, 1237 consists of only 2 factors, confirming it as 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 under 1000 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, and so on. Since 1237 is not in this range, we check whether it is divisible by smaller prime numbers and find that it has only 2 divisors.

Glossary for "Is 1237 a Prime Number?"

Prime Number: A number that has exactly two distinct positive divisors: 1 and itself. Example: 1237 is a prime number because it only has divisors of 1 and 1237.


Divisors: Numbers that divide a given number without leaving a remainder. For example, divisors of 1237 are 1 and 1237.


Composite Number: A number that has more than two divisors. Unlike prime numbers, composite numbers can be divided by numbers other than 1 and itself. Example: 1237 is a composite number if it has divisors other than 1 and itself.


Divisibility Test: A method used to check if a number is divisible by another without performing the full division. For example, checking if 1237 is divisible by smaller primes like 2, 3, 5, or 7.


Prime Factorization: Breaking down a number into the set of prime numbers that multiply to give the original number. Since 1237 is prime, its prime factorization is 1237 itself.
