To determine if 1771 is a prime number or a composite number, we simply look at the factors for 1771.
If the factors of 1771 are only 1771 and 1, then we know that 1771 is a prime number. Otherwise, 1771 is a composite number.
To explain better, if 1771 is only divisible by 1 and 1771, then it is a prime number, and if 1771 is divisible by more than 1771 and 1, then it is a composite number.
The factors of 1771 are as follows:
1, 7, 11, 23, 77, 161, 253, 1771
Therefore, since 1771 is divisible by more than one and itself, the answer to the
question "Is 1771 prime or composite?" is highlighted in blue below.
composite
Is 1772 prime or composite?
