To determine if 4048 is a prime number or a composite number, we simply look at the factors for 4048.
If the factors of 4048 are only 4048 and 1, then we know that 4048 is a prime number. Otherwise, 4048 is a composite number.
To explain better, if 4048 is only divisible by 1 and 4048, then it is a prime number, and if 4048 is divisible by more than 4048 and 1, then it is a composite number.
The factors of 4048 are as follows:
1, 2, 4, 8, 11, 16, 22, 23, 44, 46, 88, 92, 176, 184, 253, 368, 506, 1012, 2024, 4048
Therefore, since 4048 is divisible by more than one and itself, the answer to the
question "Is 4048 prime or composite?" is highlighted in blue below.
