31 37 41 43 47 are the prime numbers between 30 & 50. Scientists announced they found the highest Prime Number. It has something like one billion numerals in the number.

23 and 29 are the prime numbers between 20 and 30. The two prime numbers between 20 and 30 are 23 and 29. 23, 29 All the prime numbers will be odd so you can immediately eliminate 22, 24, 26 and 28 21 = 3x7 so that 's not prime 25 = 5x5, so that's not prime 27 = 3x3x3 so that's not prime
