Math question: What is the sum of the digits of the number 7829?

To find the sum of the digits, we add the individual digits of the number 7829. The digit 7 represents 7000, the digit 8 represents 800, the digit 2 represents 20, and the digit 9 represents 9. Adding these values, we get 7000 + 800 + 20 + 9 = 7829. Therefore, the sum of the digits is 7 + 8 + 2 + 9 = 26.

Math question: Find the smallest prime number that is a multiple of 7829.

To find the smallest prime number that is a multiple of 7829, we can start by checking if 7829 is a prime number itself. We can begin by dividing it by prime numbers less than or equal to the square root of 7829, which is approximately 88.52. However, testing division by prime numbers up to 87 shows that none of them divides evenly into 7829. Therefore, 7829 itself is a prime number and therefore, the smallest prime number that is a multiple of 7829 is 7829 itself.

What is the sum of the digits of the number 7829? (Note: The sum of the digits means adding up each individual digit in the number.)

To find the sum of the digits in the number 7829, we add 7 + 8 + 2 + 9 = 26.
