To determine if 7872 is a prime number or a composite number, we simply look at the factors for 7872.
If the factors of 7872 are only 7872 and 1, then we know that 7872 is a prime number. Otherwise, 7872 is a composite number.
To explain better, if 7872 is only divisible by 1 and 7872, then it is a prime number, and if 7872 is divisible by more than 7872 and 1, then it is a composite number.
The factors of 7872 are as follows:
1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 41, 48, 64, 82, 96, 123, 164, 192, 246, 328, 492, 656, 984, 1312, 1968, 2624, 3936, 7872
Therefore, since 7872 is divisible by more than one and itself, the answer to the
question "Is 7872 prime or composite?" is highlighted in blue below.
