To determine if 4420 is a prime number or a composite number, we simply look at the factors for 4420.
If the factors of 4420 are only 4420 and 1, then we know that 4420 is a prime number. Otherwise, 4420 is a composite number.
To explain better, if 4420 is only divisible by 1 and 4420, then it is a prime number, and if 4420 is divisible by more than 4420 and 1, then it is a composite number.
The factors of 4420 are as follows:
1, 2, 4, 5, 10, 13, 17, 20, 26, 34, 52, 65, 68, 85, 130, 170, 221, 260, 340, 442, 884, 1105, 2210, 4420
Therefore, since 4420 is divisible by more than one and itself, the answer to the
question "Is 4420 prime or composite?" is highlighted in blue below.
composite
Is 4421 prime or composite?
