Question: What is the sum of the prime factors of the number 631?

To find the prime factors of 631, we start by dividing it by the smallest prime number, 2, which doesn't give a whole number result. Moving on to the next prime number, 3, we find that 631 ÷ 3 = 210 with a remainder of 1. Continuing further, we try dividing by 5, 7, 11, and so on. However, none of these prime numbers divide 631 evenly. Therefore, 631 is a prime number, and since it has no factors other than 1 and itself, the sum of its prime factors is simply 631 + 1 = 632.

Math question: What is the sum of the digits in the number 631?

To find the sum of the digits in the number 631, we add the individual digits together. In this case, the digits are 6, 3, and 1. Adding them yields: 6 + 3 + 1 = 10. Therefore, the sum of the digits in the number 631 is 10.

Math Question: If 631 is composed of three different digits, what is the sum of the hundreds digit, twice the tens digit, and three times the ones digit?

To solve this, we'll break down 631 into its three digits. The hundreds digit is 6, the tens digit is 3, and the ones digit is 1. Now, we can calculate the sum: (6 + 2*3 + 3*1) = (6 + 6 + 3) = 15. Hence, the sum of the hundreds digit, twice the tens digit, and three times the ones digit in the number 631 is 15.
