To determine if 1527 is a prime number or a composite number, we simply look at the factors for 1527.
If the factors of 1527 are only 1527 and 1, then we know that 1527 is a prime number. Otherwise, 1527 is a composite number.
To explain better, if 1527 is only divisible by 1 and 1527, then it is a prime number, and if 1527 is divisible by more than 1527 and 1, then it is a composite number.
The factors of 1527 are as follows:
1, 3, 509, 1527
Therefore, since 1527 is divisible by more than one and itself, the answer to the
question "Is 1527 prime or composite?" is highlighted in blue below.
