Question: How can the number 1151 be expressed as the sum of two prime numbers?

To find two prime numbers whose sum is 1151, we can start by dividing 1151 by 2. Since 1151 is an odd number, the even prime number 2 cannot be a part of the sum. We then move on to check if any odd prime numbers, such as 3, are factors of 1151. However, 1151 is not divisible by 3. Next, we attempt dividing by 5, but again 1151 does not divide evenly by 5. We continue this process of testing odd prime numbers until we reach 1151/23 = 50.043, which confirms that 23 is a factor of 1151. Thus, the sum of two prime numbers equaling 1151 is 23 + 1128.

Math question: What is the sum of the prime factors of 1151?

To find the prime factors of 1151, we can divide it by prime numbers starting from 2. It is evident that 1151 is a prime number itself, as it is not divisible by any prime number less than its square root (√1151 ≈ 33.94). Therefore, the only prime factor of 1151 is 1151 itself. Hence, the sum of its prime factors is 1151. In summary, the question asks about the sum of the prime factors of 1151, which is 1151.

Math question: What is the smallest prime number greater than 1151?

To find the smallest prime number greater than 1151, we start by checking whether any number from 1152 onwards divides evenly by smaller primes. Considering the divisibility rule, we can exclude even numbers and numbers ending in 5. Then, we can skip numbers ending in 3, 7, and 9 since they won't be prime. Moving forward, we find that 1153, when divided by smaller primes, such as 2, 3, 5, 7, 11, etc., leaves a remainder indicating it is not divisible. Hence, the answer is 1153, which is the smallest prime number greater than 1151.
