'17' is a Prime number.
The sum of the digits is 1 + 7 = 8 > 7.
I am 87 .
No. .0123445553432 is far less than 100.
The prime numbers between 25 and 50 are : 23 29 31 37 41 43 47However 2 and 4 (which appear in the tens place of 5 of these numbers) are not odd numbers.We are left with 31 and 37.The sum of digits of 37 is 10 which is not less than 10;but the sum of digits of 31 is 4 which is less than 10.So, 31 it is
89
The number that is greater than 12 but less than 40 and has exactly 3 digits is 13. This number fits the criteria because it is greater than 12 and less than 40, and it has three digits (1, 3, and 0). It is the smallest 3-digit number that meets the specified conditions.
43
The new prime number, 2 multiplied by itself 57,885,161times, less one, has 17,425,170 digits.
Any prime number that has 0 as one of its digits, such as 101, 103, 107 or 109.
The prime number that is greater than 20 but less than 29 is 23.
47 is the prime number greater than 43 and less than 52.

17
The four numbers are: 113, 131, 151 and 191. For the product of the digits to be prime, the number must contain 2 ones - which greatly simplifies the exercise.
Ummm... If I am correctly interpreting the question to be asking for a prime number less than 19, whose digits added together are greater than 7, then the answer is 17. There really aren't many options here (1, 2, 3, 5, 7, 11, 13, 17), only three of which even have multiple digits (11, 13, 17). So... 177. qed?
It could be 97 which is a prime number.
The only prime number greater than 25 but less than 30 is 29. A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. In this case, 29 is not divisible by any other numbers except for 1 and itself, making it a prime number.
