To determine if 4220 is a prime number or a composite number, we simply look at the factors for 4220.
If the factors of 4220 are only 4220 and 1, then we know that 4220 is a prime number. Otherwise, 4220 is a composite number.
To explain better, if 4220 is only divisible by 1 and 4220, then it is a prime number, and if 4220 is divisible by more than 4220 and 1, then it is a composite number.
The factors of 4220 are as follows:
1, 2, 4, 5, 10, 20, 211, 422, 844, 1055, 2110, 4220
Therefore, since 4220 is divisible by more than one and itself, the answer to the
question "Is 4220 prime or composite?" is highlighted in blue below.
composite
Is 4221 prime or composite?
