Maybe the next number should be named Guinevere!

269



( Or perhaps "Vinyl Yoda" )

271

277

277 is the next prime after 271.

Reason:
272 is not prime because it is a multiple of 2 (all even numbers are multiples of two, even numbers always end in 0,2,4,6 or 8 )
273 is not prime because it is a multiple of 3 (2+7+3 = 12, 1+2 = 3 so 273 is a multiple of 3, 3 times 91)
274 is not prime (multiple of 2, even)
275 is not prime (multiple of 5, multiples of 5 end in 0 or 5)
276 is not prime (multiple of 2)
277 is prime (277 is not a multiple of 2, not even, not a multiple of 3, 2+7+7 = 16, 1+6 = 7, 7 is not a multiple of 3 so 277 is not a multiple of 3, not a multiple of 5, ends in a 7, not a multiple of 7, 21 times 7 is 147, 147 from 277 is 30, less 21 is 9, less 7 is 2. 2 is not a multiple of 7 so 277 is not a multiple of 7. 277 is not a multiple of 11 because 277 less 77 is 200, less 110 is 90, less 88 is 2. 2 is not a multiple of 11 so 277 is not a multiple of 11. 277 is not a multiple of 13 because 277 less 130 is 147 less another 130 is 17, less 13 is 4. 4 is not a multiple of 13 so 277 is not a multiple of 13. 277 is not a multiple of 17 because 277 less 170 is 107, less 17 is 90, less 85 (5 times 17 and half of 170) is 5. 5 is not a multiple of 17 so 277 is not a multiple. 17 times 17 is 170 plus 70 plus 49, which is 170 plus 119, which is 289, which is more than 277, so we are done. 277 is prime)

307. I name this prime number Guinevere.

311. I name this number LEGOLAND Ferry Boat

311 LEGOLAND Ferry Boat


OR

311 POP! Marvel Black Panther

313 POP! Animation Dragon Ball Z Future Trunks



313 is the next prime
Reason:
313 is the next Prime after 311 because 312 is even so it is a multiple of 2. 313 has no whole number factors other than 1 and itself. 313 is not a multiple of 2, it is not even. 313 is not a multiple of 3 (3 + 1 + 3 = 7 not 3,6 or 9)
