What is the largest prime factor of the number 2485?

To find the largest prime factor of 2485, we first check if it is divisible by 2, but it's not. Next, we check for divisibility by odd numbers starting from 3. Dividing 2485 by 3 gives us 828.33, and dividing by 5 gives us 497. Checking further, dividing by 7 gives 355, and dividing by 11 yields 227. As 227 is a prime number, it is the largest prime factor of 2485.

Math question: What is the largest prime number less than the square root of 2485?

To find the largest prime number less than the square root of 2485, we start by finding the square root of 2485, which is approximately 49.85. Now, we search for the largest prime number smaller than 49.85. By testing divisibility, we find that 47 is the largest prime number less than 49.85. Therefore, the largest prime number less than the square root of 2485 is 47.

Question: If 2485 is divided by the sum of its digits, multiplied by the product of its digits, and then subtracted by the square root of the sum of its prime factors, what is the result?

First, let's find the sum of the digits: 2 + 4 + 8 + 5 = 19. Then, find the product of the digits: 2 * 4 * 8 * 5 = 320. Dividing 2485 by the sum and product gives: 2485 / (19 * 320) = 0.41 (rounded to two decimal places). Next, let's determine the prime factors of 2485: 5 and 13. The sum of these prime factors is 5 + 13 = 18. Taking the square root of 18 gives √18 ≈ 4.24 (rounded to two decimal places). Finally, subtracting the square root from the division result: 0.41 - 4.24 = -3.83 (rounded to two decimal places). Therefore, the result is approximately -3.83.
