Question: What is the largest prime factor of the number formed by the digits of 7721?

To find the largest prime factor of 7721, we need to examine all possible factors. We observe that the number formed by the digits 7721 is 7721 itself. We can start by checking if this number is divisible by 2, but since it is an odd number, we can skip 2. Moving on, we check if it is divisible by 3, 5, 7, and other prime numbers. However, it turns out that 7721 is not divisible by any of these primes, which indicates that it is a prime number itself. Therefore, the largest prime factor of 7721 is the number itself, 7721.

Math question: What is the sum of the digits of the number 7721?

To find the sum of the digits, we add the individual digits together. In this case, the digits of the number 7721 are 7, 7, 2, and 1. Summing them up, we have 7 + 7 + 2 + 1 = 17. Therefore, the sum of the digits of 7721 is 17.

What is the sum of the digits of the number 7721?
