Math question: What is the sum of the digits in the number 1687?

To find the sum of the digits in 1687, we can break it down. The thousands place is 1, the hundreds place is 6, the tens place is 8, and the units place is 7. Adding these together (1 + 6 + 8 + 7) gives us a sum of 22. Therefore, the sum of the digits in 1687 is 22.

Math question: What is the sum of all the prime factors of the number 1687?

To find the prime factors of 1687, we start by dividing it by the smallest prime number, which is 2. However, 1687 is not divisible by 2. Moving to the next prime, which is 3, we find that it is also not divisible by 3. Similarly, 1687 is not divisible by 5 or 7. Continuing, we discover that it is divisible by 11. Dividing 1687 by 11, we get 153 as a quotient. Thus, the prime factors of 1687 are 11 and 153. Adding these prime factors together, we obtain 164.

Math question: What is the sum of all the even digits in the number 1687?

To find the sum of the even digits in the number 1687, we first need to identify the even digits present. We have the digit 6 which is even. Since 1, 8, and 7 are odd digits, we can exclude them. Thus, the sum of all the even digits in 1687 is 6.
