What is the largest prime factor of the number 2172?

To find the largest prime factor of 2172, we need to factorize it. 2172 can be expressed as 2^2 * 3 * 181. We start by dividing 2172 by 2 repeatedly until we can no longer divide evenly. After four divisions, we obtain 2172 / 2^4 = 135. Next, we check if 135 is divisible by any prime numbers greater than 2, but less than or equal to its square root (√135 ≈ 11.62). Starting with 3 (lowest prime number), we divide 135 by 3 and find it divides exactly, giving 135 / 3 = 45. Applying the same process, we find that 45 / 3 = 15, and 15 / 3 = 5. Now, the prime factorization of 2172 is 2^2 * 3 * 3 * 5 * 181. We note that 2, 3, 5, and 181 are all prime numbers, and the largest among them is 181. Therefore, the answer is 181, which is the largest prime factor of 2172.

Math question: What is the sum of the digits of the number 2172?
