The number 108 is a positive integer that has been a subject of interest in various mathematical and cultural contexts. To understand the factors of 108, we first need to break down this number into its prime components. The prime factorization of 108 is 2^2 * 3^3. This means that 108 can be expressed as the product of its prime factors, which are 2 and 3, each raised to certain powers.
Prime Factorization and Factors

The prime factorization of 108, as mentioned, is 2^2 * 3^3. From this, we can derive all the factors of 108 by combining the powers of 2 and 3 in all possible ways. The factors of 108 are the numbers that divide 108 without leaving a remainder. To find all the factors, we consider all combinations of the powers of 2 (from 2^0 to 2^2) and the powers of 3 (from 3^0 to 3^3) and multiply them together.
Calculating Factors
We calculate the factors by considering the combinations of powers of 2 and 3: - For 2^0 (which is 1), we have 1 * (3^0, 3^1, 3^2, 3^3) = 1, 3, 9, 27 - For 2^1 (which is 2), we have 2 * (3^0, 3^1, 3^2, 3^3) = 2, 6, 18, 54 - For 2^2 (which is 4), we have 4 * (3^0, 3^1, 3^2, 3^3) = 4, 12, 36, 108 Thus, the factors of 108 are 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, and 108.
