To determine if 725 is a prime number or a composite number, we simply look at the factors for 725.
If the factors of 725 are only 725 and 1, then we know that 725 is a prime number. Otherwise, 725 is a composite number.
To explain better, if 725 is only divisible by 1 and 725, then it is a prime number, and if 725 is divisible by more than 725 and 1, then it is a composite number.
The factors of 725 are as follows:
1, 5, 25, 29, 145, 725
Therefore, since 725 is divisible by more than one and itself, the answer to the
question "Is 725 prime or composite?" is highlighted in blue below.
composite
Is 726 prime or composite?
OK. Now you know that 725 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
