To determine if 1928 is a prime number or a composite number, we simply look at the factors for 1928.
If the factors of 1928 are only 1928 and 1, then we know that 1928 is a prime number. Otherwise, 1928 is a composite number.
To explain better, if 1928 is only divisible by 1 and 1928, then it is a prime number, and if 1928 is divisible by more than 1928 and 1, then it is a composite number.
The factors of 1928 are as follows:
1, 2, 4, 8, 241, 482, 964, 1928
Therefore, since 1928 is divisible by more than one and itself, the answer to the
question "Is 1928 prime or composite?" is highlighted in blue below.
