19 + 29 + 59 = 107
You end it when all the numbers are prime.
Other than 2, no prime numbers are even. So prime numbers can't end in even numbers. After 5, no prime number can end in 5. After 5, all prime numbers end in 1, 3, 7 or 9.
Lots of prime numbers have zeros in them. 101, 103, 107 and 109 are all prime numbers. Prime numbers can't end in zero. Numbers that end in zero are multiples of ten and have too many factors to be prime numbers.
2 and 5 are the only prime numbers that end in 2 or 5.
After 5, all prime numbers end with 1, 3, 7 or 9.
No. If they end in 4, they are even numbers and divisible by 2, and therefore are not prime.
