Is 743235 prime or composite?

A good way to instantly tell if a number is prime or composite is to learn some tricks to tell if a number divides by certain numbers. For instance, if a number is even, we know it is composite as it must be divisible by 2. If a number ends in 0 or 5, then it also cannot be prime as it would be divisible by 5. In this case, the number ends in 5, so we can tell it must be composite and cannot be prime.

Is 405 prime or composite?

405 is composite. Anything that is divisible by more than two numbers (itself and 1) is considered a composite number. Looking at the number, you can tell that it is divisible by 5 because it ends in a 5. There will be more factors, but finding one that is not 1 or itself will cause the number to be composite.


How you can tell if a number is composite?

Try dividing by some numbers. The larger the number, the more numbers you have to divide by. It is enough to test division by 2, and all the odd numbers up to the square root of the number. For very large numbers, this is not efficient. There are more efficient methods, but they are also more difficult to understand.
