To determine if 1480 is a prime number or a composite number, we simply look at the factors for 1480.
If the factors of 1480 are only 1480 and 1, then we know that 1480 is a prime number. Otherwise, 1480 is a composite number.
To explain better, if 1480 is only divisible by 1 and 1480, then it is a prime number, and if 1480 is divisible by more than 1480 and 1, then it is a composite number.
The factors of 1480 are as follows:
1, 2, 4, 5, 8, 10, 20, 37, 40, 74, 148, 185, 296, 370, 740, 1480
Therefore, since 1480 is divisible by more than one and itself, the answer to the
question "Is 1480 prime or composite?" is highlighted in blue below.
composite
Is 1481 prime or composite?
