To determine if 7440 is a prime number or a composite number, we simply look at the factors for 7440.
If the factors of 7440 are only 7440 and 1, then we know that 7440 is a prime number. Otherwise, 7440 is a composite number.
To explain better, if 7440 is only divisible by 1 and 7440, then it is a prime number, and if 7440 is divisible by more than 7440 and 1, then it is a composite number.
The factors of 7440 are as follows:
1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 31, 40, 48, 60, 62, 80, 93, 120, 124, 155, 186, 240, 248, 310, 372, 465, 496, 620, 744, 930, 1240, 1488, 1860, 2480, 3720, 7440
Therefore, since 7440 is divisible by more than one and itself, the answer to the
question "Is 7440 prime or composite?" is highlighted in blue below.
