Math question: What is the sum of the digits of the number 6898?

To find the sum of the digits, we break down the number 6898 into its individual digits: 6, 8, 9, and 8. Adding these together, we get 6 + 8 + 9 + 8 = 31. Therefore, the sum of the digits of the number 6898 is 31.

What is the smallest prime number that can be written using the digits of the number 6898?

The number 6898 has four digits: 6, 8, 9, and 8. We can rearrange these digits to form different numbers, and we need to determine if any of these permutations are prime numbers. Starting with the smallest possible number, 6889 is not prime as it is divisible by 13. Next, 6898 (the original number) is divisible by 2 and hence not prime. Similarly, 8968 can be divided by 7 and is not prime either. Lastly, 8986 is divisible by 2 and 37, making it also not prime. Therefore, there is no prime number that can be constructed using the digits of the number 6898.

What is the value of 6898 when it is multiplied by its reverse, divided by the sum of its digits, and then subtracted by the square root of its closest prime factor?

To find the value, we first reverse 6898 to get 8986. Multiplying these numbers, we get 68,878,228. The sum of the digits of 6898 is 6+8+9+8=31. Dividing the product by 31 results in 2,226,072.516. The closest prime factor of 6898 is 71. Taking the square root of 71 gives 8.426. Finally, subtracting this value from 2,226,072.516 gives 2,226,064.09. Thus, the final value after all the operations is 2,226,064.09.
