Math question: What is the largest prime factor of the number 2440?

To find the largest prime factor of 2440, we can start by dividing it by the smallest prime number, 2, repeatedly until we reach an odd number. Dividing 2440 by 2 gives 1220. Again, dividing 1220 by 2 gives 610. By repeating this process, we find that dividing 610 by 2 gives 305, which is a multiple of 5. Further dividing 305 by 5 gives 61, which is a prime number. Hence, the largest prime factor of 2440 is 61.

Math question: If 2440 is multiplied by 8 and then divided by 20, what is the final result?

To find the final result, we first multiply 2440 by 8: 2440 * 8 = 19,520. Then, we divide the product by 20: 19,520 / 20 = 976. Therefore, the final result is 976.

Math question: What is the sum of all positive integers less than or equal to 2440 that are divisible by both 4 and 5?

To find the sum, we need to determine the number of terms and then find their average. For a number to be divisible by both 4 and 5, it must be divisible by their least common multiple, which is 20. The largest multiple of 20 less than or equal to 2440 is 2440 itself. Dividing 2440 by 20 gives us 122. Hence, there are 122 terms. Now, we can calculate their average: sum = (first term + last term) × number of terms / 2. The first term is 20, the last term is 2440, and there are 122 terms. Thus, the sum = (20 + 2440) × 122 / 2 = 256,640. Therefore, the sum of all positive integers less than or equal to 2440 that are divisible by both 4 and 5 is 256,640.
