To determine if 1542 is a prime number or a composite number, we simply look at the factors for 1542.
If the factors of 1542 are only 1542 and 1, then we know that 1542 is a prime number. Otherwise, 1542 is a composite number.
To explain better, if 1542 is only divisible by 1 and 1542, then it is a prime number, and if 1542 is divisible by more than 1542 and 1, then it is a composite number.
The factors of 1542 are as follows:
1, 2, 3, 6, 257, 514, 771, 1542
Therefore, since 1542 is divisible by more than one and itself, the answer to the
question "Is 1542 prime or composite?" is highlighted in blue below.
