Question: What is the sum of all the odd numbers obtained by removing each digit from the number 8170?

To find the sum, we need to remove each digit from 8170 (8, 1, 7, and 0) and consider the odd numbers obtained: 1 and 7. The sum of these odd numbers is 1 + 7 = 8.

Math question: What is the sum of all the odd numbers between 8170 and 1, inclusively?

To find the sum of odd numbers, we can use the formula S = (n/2)(2a + (n-1)d), where S is the sum, n is the number of terms, a is the first term, and d is the common difference. In this case, the first term is 8171 and the common difference is 2, as we are considering only odd numbers. The last term can be calculated using the formula L = a + (n-1)d, which gives L = 1. Substituting these values, we get n = (1 - 8171) / 2 = -4085, which implies there are 4086 terms. Therefore, the sum S = (4086/2)(2(8171) + (4086-1)(2)). Evaluating this expression yields S = 66,364,761.

Math question: What is the smallest prime factor of 8170?

To find the smallest prime factor of 8170, we can begin by dividing it by the smallest prime number, 2. The result is 4085. Since 4085 is an odd number, we proceed to divide it by the next prime number, 3. Again, the result is 1361. We continue dividing by prime numbers until we find the smallest prime factor. Dividing 1361 by 7 gives us 194 remainder 3. Dividing by 11 gives us 124 remainder 17, and dividing by 13 results in 94 remainder 8. Finally, dividing by 17 yields 80 remainder 1. Therefore, the smallest prime factor of 8170 is 17.
