To determine if 1392 is a prime number or a composite number, we simply look at the factors for 1392.
If the factors of 1392 are only 1392 and 1, then we know that 1392 is a prime number. Otherwise, 1392 is a composite number.
To explain better, if 1392 is only divisible by 1 and 1392, then it is a prime number, and if 1392 is divisible by more than 1392 and 1, then it is a composite number.
The factors of 1392 are as follows:
1, 2, 3, 4, 6, 8, 12, 16, 24, 29, 48, 58, 87, 116, 174, 232, 348, 464, 696, 1392
Therefore, since 1392 is divisible by more than one and itself, the answer to the
question "Is 1392 prime or composite?" is highlighted in blue below.
composite
Is 1393 prime or composite?
