Math Question: What is the sum of all the prime factors of the number 197?

To find the prime factors of 197, we start by dividing it by the smallest prime number, 2, which is not a factor. Then we try dividing it by the next prime number, 3, which is also not a factor. Continuing this process, we find that 197 is only divisible by itself (197) and 1. Hence, the prime factors of 197 are only 1 and 197. To find their sum, we add 1 and 197, which equals 198. Therefore, the sum of all the prime factors of 197 is 198.

Math question: If a number is equal to 3 times another number plus 1, and the sum of the two numbers is 66, what is the number?

Let's say the smaller number is x. According to the given condition, the larger number would be 3x + 1. To find the value of x, we need to set up an equation. Since the sum of the two numbers is 66, we can form the equation: x + (3x + 1) = 66. Simplifying, we get 4x + 1 = 66. By subtracting 1 from both sides, we get 4x = 65. Finally, by dividing both sides by 4, we find x = 16.25. However, x represents a number, so the final answer is 16.25 rounded to the nearest whole number, which is 16.

Math question: What is the sum of the digits of the number obtained by raising 197 to the power of 3?

To find the cube of 197, we multiply it by itself three times. Therefore, 197 raised to the power of 3 can be written as 197 × 197 × 197. Calculating the result gives us 7,754,973. Now, let's find the sum of its digits. We add 7+7+5+4+9+7+3, which equals 42. Hence, the sum of the digits of 197 raised to the power of 3 is 42.
