To determine if 6920 is a prime number or a composite number, we simply look at the factors for 6920.
If the factors of 6920 are only 6920 and 1, then we know that 6920 is a prime number. Otherwise, 6920 is a composite number.
To explain better, if 6920 is only divisible by 1 and 6920, then it is a prime number, and if 6920 is divisible by more than 6920 and 1, then it is a composite number.
The factors of 6920 are as follows:
1, 2, 4, 5, 8, 10, 20, 40, 173, 346, 692, 865, 1384, 1730, 3460, 6920
Therefore, since 6920 is divisible by more than one and itself, the answer to the
question "Is 6920 prime or composite?" is highlighted in blue below.
composite
Is 6921 prime or composite?
