Factors of 1212 Solved Examples

Example 1: How many factors are there for 1212?
Solution:
The factors of 1212 are too many, therefore if we can find the prime factorization of 1212, then the total number of factors can be calculated using the formula shown below.
If the prime factorization of the number is a^{x} × b^{y} × c^{z} where a, b, c are prime, then the total number of factors can be given by (x + 1)(y + 1)(z + 1).
Prime Factorization of 1212 = 2^{2} × 3^{1} × 101^{1}
Therefore, the total number of factors are (2 + 1) × (1 + 1) × (1 + 1) = 3 × 2 × 2 = 12
