To determine if 9940 is a prime number or a composite number, we simply look at the factors for 9940.
If the factors of 9940 are only 9940 and 1, then we know that 9940 is a prime number. Otherwise, 9940 is a composite number.
To explain better, if 9940 is only divisible by 1 and 9940, then it is a prime number, and if 9940 is divisible by more than 9940 and 1, then it is a composite number.
The factors of 9940 are as follows:
1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 71, 140, 142, 284, 355, 497, 710, 994, 1420, 1988, 2485, 4970, 9940
Therefore, since 9940 is divisible by more than one and itself, the answer to the
question "Is 9940 prime or composite?" is highlighted in blue below.
