To determine if 3651 is a prime number or a composite number, we simply look at the factors for 3651.
If the factors of 3651 are only 3651 and 1, then we know that 3651 is a prime number. Otherwise, 3651 is a composite number.
To explain better, if 3651 is only divisible by 1 and 3651, then it is a prime number, and if 3651 is divisible by more than 3651 and 1, then it is a composite number.
The factors of 3651 are as follows:
1, 3, 1217, 3651
Therefore, since 3651 is divisible by more than one and itself, the answer to the
question "Is 3651 prime or composite?" is highlighted in blue below.
composite
Is 3652 prime or composite?
