How many two-digit numbers can be formed using the four digits 8, 1, 4, and 6 without repetition?

To determine the number of two-digit numbers, we start by considering the options for the tens digit. Since we cannot repeat digits, there are 3 choices left after selecting the tens digit. For each choice of the tens digit, there remain 3 choices for the units digit. Thus, the total number of two-digit numbers without repetition is 3 × 3 = 9.

What is the largest prime factor of the number 8146? Provide a detailed explanation.

To find the largest prime factor of 8146, we start by dividing it by the smallest prime number, which is 2. The result is 4073. Next, we check if 4073 is divisible by 3, 5, 7, and further prime numbers, but none of them evenly divide it. Moving on, we test for divisibility by the next prime number, which is 11. Luckily, 4073 is divisible by 11, giving us 370 as the quotient. Continuing the process, we find that 370 is divisible by 2, resulting in 185. Trying other prime numbers, we realize that 185 is divisible by 5, yielding 37. Lastly, we divide 37 by 2 and see that it is not divisible by any of the remaining prime numbers. Thus, the largest prime factor of 8146 is 37.

Math question: What is the sum of the digits in the number 8146?

To find the sum of the digits in 8146, we break down the number into its individual digits: 8, 1, 4, and 6. Adding these digits together, we get 8 + 1 + 4 + 6 = 19. Therefore, the sum of the digits in the number 8146 is 19.
