Math question: What is the largest prime factor of the number 6449?

To find the largest prime factor of 6449, we can start by checking if any prime numbers divide it evenly. Dividing 6449 by 2, 3, 5, 7, and other primes, we don't get an integer result. Hence, we need to resort to a more systematic approach. Let's begin by calculating the square root of 6449, which is approximately 80.27. Starting from 2 and moving upwards, we check each number to see if it divides 6449 evenly. After checking prime numbers up to 80, we find that 83 is the smallest prime that divides 6449 without leaving a remainder. Hence, the largest prime factor of 6449 is 83.

What is the smallest prime factor of the number obtained by shuffling the digits of 6449 and subtracting the original number from it?

By shuffling the digits of 6449, we obtain 9464. Subtracting the original number from it, we get 9464 - 6449 = 3015. The smallest prime factor of 3015 is 3.

What is the largest prime factor of the number 6449?

To find the largest prime factor of 6449, we first check if it is divisible by prime numbers starting from 2. Dividing 6449 by 2, we get 3224 remainder 1. Dividing by 3, 4, 5, 6, 7, and so on, we find no exact divisors. Continuing to divide by primes up to the square root of 6449, which is approximately 80, we find that the largest prime factor is 89.
