To determine if 5561 is a prime number or a composite number, we simply look at the factors for 5561.
If the factors of 5561 are only 5561 and 1, then we know that 5561 is a prime number. Otherwise, 5561 is a composite number.
To explain better, if 5561 is only divisible by 1 and 5561, then it is a prime number, and if 5561 is divisible by more than 5561 and 1, then it is a composite number.
The factors of 5561 are as follows:
1, 67, 83, 5561
Therefore, since 5561 is divisible by more than one and itself, the answer to the
question "Is 5561 prime or composite?" is highlighted in blue below.
composite
Is 5562 prime or composite?
