To determine if 3648 is a prime number or a composite number, we simply look at the factors for 3648.
If the factors of 3648 are only 3648 and 1, then we know that 3648 is a prime number. Otherwise, 3648 is a composite number.
To explain better, if 3648 is only divisible by 1 and 3648, then it is a prime number, and if 3648 is divisible by more than 3648 and 1, then it is a composite number.
The factors of 3648 are as follows:
1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 32, 38, 48, 57, 64, 76, 96, 114, 152, 192, 228, 304, 456, 608, 912, 1216, 1824, 3648
Therefore, since 3648 is divisible by more than one and itself, the answer to the
question "Is 3648 prime or composite?" is highlighted in blue below.
