Math question: What is the factorial of the sum of the first three odd prime numbers (5, 7, 11) multiplied by 2,047?

To find the factorial of the sum of 5, 7, and 11 (which is 23), we multiply it by 2,047. The factorial of 23 is calculated by multiplying all positive integers from 1 to 23: 23! = 1 x 2 x 3 x ... x 23. The resulting value is then multiplied by 2,047.

Math Question: What is the sum of all the positive even numbers less than or equal to 2047?

To find the sum, we first need to determine the number of even numbers less than or equal to 2047. The largest even number that fits this criteria is 2046. Now, we can use the formula for the sum of an arithmetic series: Sn = n/2 * (a + b), where n represents the number of terms, a is the first term, and b is the last term. Here, a = 2 (since it's the first positive even number), b = 2046, and n represents the number of even numbers. We can find n using the formula: n = (b - a)/2 + 1. Plugging in the values, we have n = (2046 - 2)/2 + 1 = 1023. Now we can calculate the sum using the formula Sn = n/2 * (a + b): Sn = 1023/2 * (2 + 2046) = 1023/2 * 2048 = 1,048,064. Hence, the sum of all positive even numbers less than or equal to 2047 is 1,048,064.

Math Question: Can 2047 be expressed as the product of two prime numbers larger than 2?

To determine if 2047 can be expressed as the product of two prime numbers larger than 2, let's check. First, we divide 2047 by the smallest prime number larger than 2 (i.e., 3). However, 2047 is not divisible by 3 since the sum of its digits is not divisible by 3. Next, we try the next prime number (i.e., 5), but it is also not a factor of 2047. Repeating the process for all prime numbers larger than 2, we find that 2047 cannot be expressed as the product of two prime numbers larger than 2. Therefore, the answer is no, 2047 cannot be expressed as the product of two prime numbers larger than 2.
