To determine if 1248 is a prime number or a composite number, we simply look at the factors for 1248.
If the factors of 1248 are only 1248 and 1, then we know that 1248 is a prime number. Otherwise, 1248 is a composite number.
To explain better, if 1248 is only divisible by 1 and 1248, then it is a prime number, and if 1248 is divisible by more than 1248 and 1, then it is a composite number.
The factors of 1248 are as follows:
1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 32, 39, 48, 52, 78, 96, 104, 156, 208, 312, 416, 624, 1248
Therefore, since 1248 is divisible by more than one and itself, the answer to the
question "Is 1248 prime or composite?" is highlighted in blue below.
composite
