Math Question: What is the smallest prime factor greater than 2 of the number formed by repeating the digit 8 four times, i.e., 8222?

To find the smallest prime factor of 8222, we can calculate the prime factorization of this number. By testing various prime numbers, we find that 8222 = 2 × 3 × 29 × 47. Therefore, the smallest prime factor greater than 2 of 8222 is 3.

Math question: What is the sum of the digits in the number 8222?

To find the sum of the digits, we add 8 + 2 + 2 + 2. Therefore, the sum of the digits in 8222 is 14. Explanation: Starting with the leftmost digit, we have 8, then 2, 2, and 2. By adding these digits together, we get the sum of 14.

Math question: What is the smallest prime factor of the number obtained by multiplying the sum of the digits of 8222 with its reverse?

To find the product of the sum of the digits of 8222 (i.e., 8+2+2+2 = 14) and its reverse (i.e., 2228), we have 14 * 2228 = 31192. Analyzing this resulting number, we observe that the smallest prime factor is 2, as it divides evenly into 31192. Therefore, the answer is 2.
