To determine if 4380 is a prime number or a composite number, we simply look at the factors for 4380.
If the factors of 4380 are only 4380 and 1, then we know that 4380 is a prime number. Otherwise, 4380 is a composite number.
To explain better, if 4380 is only divisible by 1 and 4380, then it is a prime number, and if 4380 is divisible by more than 4380 and 1, then it is a composite number.
The factors of 4380 are as follows:
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60, 73, 146, 219, 292, 365, 438, 730, 876, 1095, 1460, 2190, 4380
Therefore, since 4380 is divisible by more than one and itself, the answer to the
question "Is 4380 prime or composite?" is highlighted in blue below.
composite
