Answer 2

Answer: 51

Step-by-step explanation: A prime number is a number that is greater than 1 and it has two factors which are 1 and itself.

23 is a prime number because it has no other factors besides 1 and 23. In other words, there is no other number multiplied by a number than will equal 23 so we call it a prime number.
