A number to be a prime number should follow the criteria, which is that it should not have factors more than 2. Here, 1234567 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 1234567 would simply be:

Divisors of 1234567 = 1, 127, 9713, 1234567
Number of divisors = 4

The number 1234567 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.

Thus, 1234567 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, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

1234567 is not present in the list, and it is not a prime number.
 

This method is only used for a non-prime number/composite number. Since 1234567 is a composite number, the prime factorization for 1234567 is:

Factors of 1234567 = 127 × 9713
 

• Prime Number: A natural number greater than 1 that has no positive divisors other than 1 and itself. Prime numbers are fundamental in number theory and are used in various applications, such as digital security.

• Composite Number: A positive integer greater than 1 that has more than two distinct divisors. Unlike prime numbers, composite numbers can be factored into smaller positive integers.

• Divisors: The numbers that divide a given number exactly without leaving a remainder. For example, the divisors of 1234567 are 1, 127, 9713, and 1234567.

• Prime Factorization: The expression of a number as the product of its prime factors. For example, the prime factorization of 1234567 is 127 × 9713.

• Divisibility Test: A method used to check if one number can be divided by another without leaving a remainder. For example, testing if 1234567 can be divided by small prime numbers like 2, 3, or 5.
