Math Question: What is the sum of the digits in the prime factorization of 8720?

To find the prime factorization of 8720, we factorize it as 8720 = 2 × 2 × 2 × 2 × 5 × 109. Summing up the digits, we have 2 + 2 + 2 + 2 + 5 + 1 + 0 + 9 = 23. Therefore, the sum of the digits in the prime factorization of 8720 is 23. In prime factorization, we break down a number into its prime factors. For 8720, we divide it by 2 successively, resulting in the prime factor of 2 appearing four times. The number 5 also emerges as a prime factor, and further, we obtain a prime factor of 109. To determine the sum of the digits, we add up the digits in each of the prime factors. After calculating, we find the sum to be 23.

Math Question: What is the sum of the digits in the number 8720?

To find the sum of the digits in 8720, we add the individual digits together. The digit 8 has a value of 8, 7 has a value of 7, 2 has a value of 2, and 0 has a value of 0. Therefore, the sum of the digits in 8720 is 8 + 7 + 2 + 0 = 17.

What is the smallest integer that divides the number 8720 and leaves a remainder of 8 when divided by 9?

To find the answer, we can consider the divisibility rule for 9. The rule states that if the sum of the digits of a number is divisible by 9, then the number itself is divisible by 9. The sum of the digits in 8720 is 8+7+2+0 = 17, which is not divisible by 9. Since we want a remainder of 8, we need to increase the sum of the digits by 1. The smallest multiple of 9 greater than 17 is 18, so we add 1 to 17 to make the sum 18. Now, we can find the smallest multiple of 9 with a sum of 18 using the digit 1: 108. Adding 1 to this gives us 109. Therefore, the desired number is 8720 + 108 = 8828. Hence, the smallest integer that divides 8720 and leaves a remainder of 8 when divided by 9 is 8828.
