To determine if 7020 is a prime number or a composite number, we simply look at the factors for 7020.
If the factors of 7020 are only 7020 and 1, then we know that 7020 is a prime number. Otherwise, 7020 is a composite number.
To explain better, if 7020 is only divisible by 1 and 7020, then it is a prime number, and if 7020 is divisible by more than 7020 and 1, then it is a composite number.
The factors of 7020 are as follows:
1, 2, 3, 4, 5, 6, 9, 10, 12, 13, 15, 18, 20, 26, 27, 30, 36, 39, 45, 52, 54, 60, 65, 78, 90, 108, 117, 130, 135, 156, 180, 195, 234, 260, 270, 351, 390, 468, 540, 585, 702, 780, 1170, 1404, 1755, 2340, 3510, 7020
Therefore, since 7020 is divisible by more than one and itself, the answer to the
question "Is 7020 prime or composite?" is highlighted in blue below.
composite
Is 7021 prime or composite?
