To determine if 3728 is a prime number or a composite number, we simply look at the factors for 3728.
If the factors of 3728 are only 3728 and 1, then we know that 3728 is a prime number. Otherwise, 3728 is a composite number.
To explain better, if 3728 is only divisible by 1 and 3728, then it is a prime number, and if 3728 is divisible by more than 3728 and 1, then it is a composite number.
The factors of 3728 are as follows:
1, 2, 4, 8, 16, 233, 466, 932, 1864, 3728
