Math question: What is the sum of all the positive factors of 999?

To find the sum of all positive factors of 999, we first find the prime factorization of 999. Dividing 999 by the smallest prime number, 3, gives us 333. Continuing to divide by 3, we get 111. Then, dividing 111 by 3, we obtain 37 as a result. Since 37 is a prime number, the prime factorization of 999 is 3^3 * 37. Now, to find the sum of all factors, we can use the formula: Sum = (3^0 + 3^1 + 3^2 + 3^3) * (37^0 + 37^1). Evaluating this, we get: Sum = (1 + 3 + 9 + 27) * (1 + 37) = 40 * 38 = 1520. Therefore, the sum of all positive factors of 999 is 1520.

Math question: What is the remainder when 999 is divided by 7?

To find the remainder when 999 is divided by 7, we divide: 999 ÷ 7 = 142 with a remainder of 5. Therefore, the remainder is 5.

Math question: What is the sum of all positive divisors of the number 999?

To find the divisors of 999, we need to factorize it. In this case, 999 can be written as 3 * 3 * 3 * 37. Now, to calculate the sum of divisors, we use the formula: (3^0 + 3^1 + 3^2 + 3^3)(37^0 + 37^1). Simplifying this, we get (1+3+9+27)(1+37), which equals 40 * 38 = 1520. Therefore, the sum of all positive divisors of 999 is 1520.
