Math Question: What is the smallest prime number greater than 2355 that can be expressed as the sum of two prime numbers?

The smallest prime number greater than 2355 is 2357. To find it, we need to check all numbers greater than 2355 until we find one that satisfies the condition. By iterating through the numbers, it is determined that 2357 is prime and can be expressed as the sum of 1181 and 1176, both of which are prime numbers. Thus, 2357 is the smallest prime number greater than 2355 that can be expressed as the sum of two prime numbers.

Question: What is the sum of the digits when the number 2355 is multiplied by its reverse?

To find the product of 2355 and its reverse, we get 2355 × 5532 = 13,022,460. Now, adding the individual digits: 1 + 3 + 0 + 2 + 2 + 4 + 6 + 0 = 18. Therefore, the sum of the digits is 18.

What is the product of the prime factors of the number 2355?

The prime factorization of 2355 is 3 × 5 × 157. Therefore, the product of the prime factors is 3 × 5 × 157 = 2355.
