To determine if 3627 is a prime number or a composite number, we simply look at the factors for 3627.
If the factors of 3627 are only 3627 and 1, then we know that 3627 is a prime number. Otherwise, 3627 is a composite number.
To explain better, if 3627 is only divisible by 1 and 3627, then it is a prime number, and if 3627 is divisible by more than 3627 and 1, then it is a composite number.
The factors of 3627 are as follows:
1, 3, 9, 13, 31, 39, 93, 117, 279, 403, 1209, 3627
Therefore, since 3627 is divisible by more than one and itself, the answer to the
question "Is 3627 prime or composite?" is highlighted in blue below.
