Math question: If you add the product of the digits in the number 7783 to the sum of the digits squared, what is the result?

To find the sum of the digits, we add 7 + 7 + 8 + 3 = 25. The product of the digits is 7 × 7 × 8 × 3 = 1176. Now, the sum of the digits squared is 7^2 + 7^2 + 8^2 + 3^2 = 49 + 49 + 64 + 9 = 171. Finally, when we add the product of the digits (1176) to the sum of the digits squared (171), we get 1176 + 171 = 1347 as the result.

What is the sum of the digits when the number 7783 is multiplied by the number obtained by reversing its digits?

To find the answer, we first reverse the digits of 7783 to get 3877. Then, we multiply 7783 by 3877, which equals 30193391. The sum of the digits in 30193391 is computed by adding 3+0+1+9+3+3+9+1, which equals 29. Therefore, the sum of the digits when the number 7783 is multiplied by its reverse is 29.

What is the largest prime number less than 7783?

The largest prime number less than 7783 is 7753. To determine this, we can start dividing 7783 by decreasing prime numbers (starting from √7783) until we find a divisor. In this case, dividing by primes such as 97, 89, 83, 79, and finally 73, we discover that 73 is a divisor of 7783 with no remainder. Hence, 7783 is not a prime number, and the largest prime less than it is 7753.
