What is the sum of the digits of the number 8349 when it is divided by its reverse and multiplied by the square of its last digit?

To find the sum of the digits, we have 8 + 3 + 4 + 9 = 24. The reverse of 8349 is 9438. Dividing 8349 by 9438 gives a quotient of 0.8845. The last digit of 8349 is 9, so squaring it gives 81. Multiplying 0.8845 by 81 gives an approximate value of 71.593, rounded to 3 decimal places.

What is the largest prime factor of the number 8349?

To find the prime factorization, we start by dividing 8349 by 2, resulting in 4174.5. Since 4174.5 is not an integer, we move to the next prime number, 3. Dividing 4174.5 by 3 gives us 1391.5, still not an integer. Next, we divide by 5 and get 834.9, which is not an integer either. Continuing this process, we eventually find that the largest prime factor of 8349 is 139. To verify, we can divide 8349 by 139, and the quotient is 60, which shows that 139 is indeed a prime factor of 8349.

What is the sum of the digits in the number 8349?

To find the sum of the digits in the number 8349, we need to add each individual digit. 8 + 3 + 4 + 9 = 24 So, the sum of the digits in the number 8349 is 24.
