Question: What is the sum of the prime factors of the number 945?

To find the prime factors of 945, we start by dividing it by the smallest prime number, 2. However, 945 is not divisible by 2. Next, we divide by 3, which gives us 315. Dividing 315 by 3 again, we obtain 105. Continuing this process, we divide 105 by 3 to get 35, then divide 35 by 5 to get 7. Now, we cannot divide 7 any further as it is a prime number. Therefore, the prime factorization of 945 is 3 × 3 × 5 × 7. Finally, to find the sum of these prime factors, we add them: 3 + 3 + 5 + 7 = 18. Therefore, the sum of the prime factors of 945 is 18.

Math question: What is the sum of the digits of the integer 945?

To find the sum of the digits in the number 945, we add the individual digits together. In this case, the digit 9 + 4 + 5 equals 18. Thus, the sum of the digits in the number 945 is 18.

What is the product of the prime factors of the number 945?

The prime factorization of 945 is 3 × 3 × 3 × 5 × 7. To find the product of these prime factors, we multiply them: 3 × 3 × 3 × 5 × 7 = 945. So, the product of the prime factors of 945 is 945.
