99 = 32*11
99 = 32*11
99 = 32*11
99 = 32*11
2 x 52 x 7 = 350

To find the common factors of 42 and 231, we first need to find the prime factorization of each number. The prime factorization of 42 is 2 x 3 x 7, and the prime factorization of 231 is 3 x 7 x 11. The common factors of 42 and 231 are the prime numbers that appear in both factorizations, which are 3 and 7. Therefore, the two common factors of 42 and 231 are 3 and 7.
The common factors of 264 and 504 are the numbers that can evenly divide both 264 and 504 without leaving a remainder. To find the common factors, we first need to find the prime factorization of each number. The prime factorization of 264 is 2^3 * 3 * 11, and the prime factorization of 504 is 2^3 * 3^2 * 7. The common factors are the common prime factors raised to the lowest power they appear in both numbers, which in this case are 2^3 and 3. Therefore, the common factors of 264 and 504 are 2^3 (8) and 3.
