To determine if 7638 is a prime number or a composite number, we simply look at the factors for 7638.
If the factors of 7638 are only 7638 and 1, then we know that 7638 is a prime number. Otherwise, 7638 is a composite number.
To explain better, if 7638 is only divisible by 1 and 7638, then it is a prime number, and if 7638 is divisible by more than 7638 and 1, then it is a composite number.
The factors of 7638 are as follows:
1, 2, 3, 6, 19, 38, 57, 67, 114, 134, 201, 402, 1273, 2546, 3819, 7638
Therefore, since 7638 is divisible by more than one and itself, the answer to the
question "Is 7638 prime or composite?" is highlighted in blue below.
