If a number is divisible by anything other than itself and 1, it's composite.
A number can be factored to determine whether it is prime or composite. A prime number has exactly 2 factors, 1 and the number itself. A composite number has more than two factors.
You use divisibility rules t determine whether a particular number is (or is not) a factor of another number. If it is a factor, you can reduce the numbers involved to smaller numbers.You might want to find factors to simplify fractions or to add or subtract factions.
To determine if a number is divisible by 2356, you can use the divisibility rules for its prime factors. First, factor 2356 into its prime components, which are 2, 4, 589. Check if the number is even (for 2), if it ends in 0 or 5 (for 5), and apply the rules for 589 as needed. For a number W, you would follow its specific divisibility rules, which may involve checking for factors or specific modular conditions.
To determine if 2558 is a prime number, you would typically test divisibility by numbers up to the square root of 2558. The square root of 2558 is approximately 50.58. Therefore, you would test divisibility by prime numbers up to 51. The greatest prime number less than or equal to 51 is 47, so you would test divisibility by 47 to determine if 2558 is a prime number.
That depends what you need to "solve". If what you want to do is check whether a number is prime or composite, check whether it is divisible by 2, and then by all odd numbers up to the square root of your number. For example, for numbers up to 120, you only need to check whether they are divisible by 2, 3, 5, 7 (9 is composite, so you don't really need to check divisibility by 9). If your number is divisible by any such number, then it is composite; otherwise it is a prime. There are more efficient methods, but they are also more complicated, and it really only makes sense to use them for much larger numbers.
It's composite
evaluating test results.
I suggest you try dividing it by different numbers, and see whether it is divisible. If you find a divisor, then it is composite. Otherwise it is a prime. For numbers up to 120, it is sufficient to test divisibility by 2, 3, 5, and 7.
If it has more than two factors.
A number can be factored to determine whether it is prime or composite. A prime number has exactly 2 factors, 1 and the number itself. A composite number has more than two factors.
By trying out whether you can divide it by different numbers. For one- or two-digit numbers, it is enough to test divisibility by 2, 3, 5, 7.

Not sure what you meant, but 242 is not divisible by 3. By adding all digits, you can determine whether it is a multiple of 3 or not.

3 and 9. And they divide into 123456789 whether or not you use divisibility rules!
