Question: What is the sum of the digits in the number 2405?

To find the sum of the digits, we break down the number into its individual digits and add them together. Considering the number 2405, we have 2 + 4 + 0 + 5 = 11. Therefore, the sum of the digits in 2405 is 11.

Math question: What is the sum of the first five multiples of 2405?

To find the sum of the first five multiples of 2405, we need to calculate 2405 + 2 * 2405 + 3 * 2405 + 4 * 2405 + 5 * 2405. Simplifying, this becomes 2405(1 + 2 + 3 + 4 + 5) which is 2405 * 15 = 36,075. Hence, the sum of the first five multiples of 2405 is 36,075.

Math question: What is the largest prime factor of 2405?

To find the largest prime factor of 2405, we start by checking if 2 divides it, but since it's odd, it doesn't. Next, we try dividing by 3, and it works evenly yielding 801. Continuing, dividing 801 by 3 gives us 267, and again, dividing 267 by 3 results in 89, which is a prime number. Thus, the largest prime factor of 2405 is 89. This is determined by performing prime factorization and repeatedly dividing by the lowest prime numbers until we obtain a prime factor.
