Largest known prime number
I reverted your edit; changes to articles should be for the benefit of the general reader. There is a reference desk which can help you with queries, though they should be intended for improving a Wikipedia article. And since you ask, I believe that 1013 is a prime; its square root is 31.8 and it is not divisible by 2, 3, 5, 7, 9, 11, 13, 17, 19, 23, 29 or 31. Best, Wham2001 (talk) 16:57, 1 January 2019 (UTC)
