To determine if 8742 is a prime number or a composite number, we simply look at the factors for 8742.
If the factors of 8742 are only 8742 and 1, then we know that 8742 is a prime number. Otherwise, 8742 is a composite number.
To explain better, if 8742 is only divisible by 1 and 8742, then it is a prime number, and if 8742 is divisible by more than 8742 and 1, then it is a composite number.
The factors of 8742 are as follows:
1, 2, 3, 6, 31, 47, 62, 93, 94, 141, 186, 282, 1457, 2914, 4371, 8742
Therefore, since 8742 is divisible by more than one and itself, the answer to the
question "Is 8742 prime or composite?" is highlighted in blue below.
