Math question: What is the sum of the prime factors of 2169?

To find the prime factors of 2169, we start by dividing it by the smallest prime number, which is 3. The quotient is 723. Dividing 723 by 3 again gives us 241. Now, 241 is a prime number, so the prime factors of 2169 are 3 and 241. The sum of these prime factors is 3 + 241 = 244. Therefore, the answer is that the sum of the prime factors of 2169 is 244.

Question: A three-digit number is formed using the digits 2, 1, 6, and 9 without any repetition. What is the sum of all possible three-digit numbers formed?

Firstly, we can determine the total number of three-digit numbers that can be formed using these digits. We have 4 choices for the hundreds digit, 3 choices for the tens digit (after using one digit for the hundreds place), and 2 choices for the units digit (after using two digits for the hundreds and tens places). Therefore, the total number of three-digit numbers that can be formed is 4 × 3 × 2 = 24. To find the sum of all these numbers, we can consider the digit positions. Each digit appears the same number of times (6 times) in each position (hundreds, tens, and units). Thus, the sum of all digits in the hundreds place will be (6 × 2) + (6 × 1) + (6 × 6) + (6 × 9) = 156. Similarly, the sum of all digits in the tens place and units place will also be 156. Multiplying the sum of digits in each place (156) by the number of digits in each place (6) and summing these products gives us the desired sum: 156 × 6 + 156 × 6 + 156 × 6 = 2808. Therefore, the sum of all possible three-digit numbers formed using the digits 2, 1, 6, and 9 is 2808.

Math question: What is the sum of the digits in the number 2169?

To find the sum of the digits in the number 2169, we go through each digit and add them together. Breaking down 2169, we have 2 + 1 + 6 + 9 = 18. Hence, the sum of the digits in 2169 is 18. This can be useful in various mathematical computations, such as digit-sum techniques, casting out nines, or in digital roots. Additionally, knowing the sum of digits can help us gain insights into the divisibility properties of a number.
