Math question: What is the smallest positive integer that can be added to 7789 to make it divisible by 9?

To determine the smallest positive integer that can be added to 7789 to make it divisible by 9, we can add the digits together: 7 + 7 + 8 + 9 = 31. Since 31 is not divisible by 9, we need to find the next multiple of 9, which is 36. Thus, to make 7789 divisible by 9, we need to add 36. Adding 36 to 7789 results in 7825. Therefore, 7825 is the smallest positive integer that can be added to 7789 to make it divisible by 9.

Math question: If the number 7789 is multiplied by 5 and then divided by 2, what is the final result?

To find the result, we multiply 7789 by 5 giving us 38945. Then, we divide 38945 by 2 which yields 19472.5. Therefore, the final result after these calculations is 19472.5.

Math question: What is the sum of the prime factors of 7789?

To find the prime factors of 7789, we first need to determine if the number itself is prime. By dividing it by prime numbers starting from 2, we see that 7789 is not divisible by 2, 3, or 5. Checking further, we find that the smallest prime factor of 7789 is 83. Therefore, the sum of its prime factors is 83. Explanation: A prime factor is a prime number that divides another number without leaving a remainder. In this case, we explored if 7789 can be divided by prime numbers until we found the smallest prime factor, which is 83. The sum of the prime factors is simply the addition of all prime factors, and since there is only one prime factor, the sum is equal to 83.
