Question: If the sum of the digits of a positive integer is 18, and the number is divisible by 7, what is the smallest possible value for this integer?

To find the smallest possible integer, we can start by checking if 1827 is divisible by 7. Summing its digits, we get 1+8+2+7 = 18. Since 1827 is divisible by 7, it satisfies that condition. Now, let's find a smaller number by rearranging the digits. Swapping the last two digits, we get 1872. Checking if 1872 is divisible by 7, its digit sum is 1+8+7+2=18. Therefore, the smallest possible integer satisfying the conditions is 1872.

Math question: What is the sum of the digits of the number obtained by multiplying 1827 by its reversed form?

First, we reverse 1827 to get 7281. Next, we multiply these two numbers: 1827 × 7281 = 13301487. Now, when we add up the digits of the product: 1 + 3 + 3 + 0 + 1 + 4 + 8 + 7 = 27. Therefore, the sum of the digits of the number obtained by multiplying 1827 by its reversed form is 27.

Math question: What is the sum of all the digits of the number 1827?

The number 1827 can be represented as 1 + 8 + 2 + 7 = 18.
