To determine if 3561 is a prime number or a composite number, we simply look at the factors for 3561.
If the factors of 3561 are only 3561 and 1, then we know that 3561 is a prime number. Otherwise, 3561 is a composite number.
To explain better, if 3561 is only divisible by 1 and 3561, then it is a prime number, and if 3561 is divisible by more than 3561 and 1, then it is a composite number.
The factors of 3561 are as follows:
1, 3, 1187, 3561
Therefore, since 3561 is divisible by more than one and itself, the answer to the
question "Is 3561 prime or composite?" is highlighted in blue below.
composite
Is 3562 prime or composite?
