To determine if 4257 is a prime number or a composite number, we simply look at the factors for 4257.
If the factors of 4257 are only 4257 and 1, then we know that 4257 is a prime number. Otherwise, 4257 is a composite number.
To explain better, if 4257 is only divisible by 1 and 4257, then it is a prime number, and if 4257 is divisible by more than 4257 and 1, then it is a composite number.
The factors of 4257 are as follows:
1, 3, 9, 11, 33, 43, 99, 129, 387, 473, 1419, 4257
Therefore, since 4257 is divisible by more than one and itself, the answer to the
question "Is 4257 prime or composite?" is highlighted in blue below.
