To determine if 1755 is a prime number or a composite number, we simply look at the factors for 1755.
If the factors of 1755 are only 1755 and 1, then we know that 1755 is a prime number. Otherwise, 1755 is a composite number.
To explain better, if 1755 is only divisible by 1 and 1755, then it is a prime number, and if 1755 is divisible by more than 1755 and 1, then it is a composite number.
The factors of 1755 are as follows:
1, 3, 5, 9, 13, 15, 27, 39, 45, 65, 117, 135, 195, 351, 585, 1755
Therefore, since 1755 is divisible by more than one and itself, the answer to the
question "Is 1755 prime or composite?" is highlighted in blue below.
composite
Is 1756 prime or composite?
