Question: The number 8280 is divisible by a certain two-digit number. If the sum of the digits of this two-digit number is 13, and their difference is 3, what is that two-digit number?

Let's call the tens digit of the number as x and the units digit as y. We know that the number can be expressed as 10x + y. According to the given conditions, we have the following equations: x + y = 13 and x - y = 3. Solving these simultaneous equations, we find that 2x = 16, which implies x = 8. Substituting the value of x in one of the equations, we find that y = 13 - 8 = 5. Therefore, the two-digit number is 85, and it divides 8280.

Math question: If the number 8280 is divided by the difference between the sum of its digits and the product of its digits, what is the quotient?

To find the sum of the digits of 8280, we have 8 + 2 + 8 + 0 = 18. The product of the digits is 8 x 2 x 8 x 0 = 0. Therefore, the difference between the sum and the product is 18 - 0 = 18. Now, dividing 8280 by 18 gives us 8280 ÷ 18 = 460. Consequently, the quotient is 460.

Question: What is the smallest prime number that can be evenly divided by 8280?

To find the smallest prime number that can evenly divide 8280, we can begin checking divisibility starting with 2, since 2 is the smallest prime. If we divide 8280 by 2, we get 4140. This result is divisible by 2 again, giving 2070. Continuing this process, we find that dividing by 2 successively gives 1035, 517.5, and eventually 258.75, which is not an integer. Therefore, the smallest prime number that can evenly divide 8280 is 2.
