To determine if 1528 is a prime number or a composite number, we simply look at the factors for 1528.
If the factors of 1528 are only 1528 and 1, then we know that 1528 is a prime number. Otherwise, 1528 is a composite number.
To explain better, if 1528 is only divisible by 1 and 1528, then it is a prime number, and if 1528 is divisible by more than 1528 and 1, then it is a composite number.
The factors of 1528 are as follows:
1, 2, 4, 8, 191, 382, 764, 1528
Therefore, since 1528 is divisible by more than one and itself, the answer to the
question "Is 1528 prime or composite?" is highlighted in blue below.
