To determine if 4230 is a prime number or a composite number, we simply look at the factors for 4230.
If the factors of 4230 are only 4230 and 1, then we know that 4230 is a prime number. Otherwise, 4230 is a composite number.
To explain better, if 4230 is only divisible by 1 and 4230, then it is a prime number, and if 4230 is divisible by more than 4230 and 1, then it is a composite number.
The factors of 4230 are as follows:
1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 47, 90, 94, 141, 235, 282, 423, 470, 705, 846, 1410, 2115, 4230
Therefore, since 4230 is divisible by more than one and itself, the answer to the
question "Is 4230 prime or composite?" is highlighted in blue below.
composite
