To determine if 3872 is a prime number or a composite number, we simply look at the factors for 3872.
If the factors of 3872 are only 3872 and 1, then we know that 3872 is a prime number. Otherwise, 3872 is a composite number.
To explain better, if 3872 is only divisible by 1 and 3872, then it is a prime number, and if 3872 is divisible by more than 3872 and 1, then it is a composite number.
The factors of 3872 are as follows:
1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 121, 176, 242, 352, 484, 968, 1936, 3872
Therefore, since 3872 is divisible by more than one and itself, the answer to the
question "Is 3872 prime or composite?" is highlighted in blue below.
