They are 10 and 15
The prime integers between 10 and 25 are 11, 13, 17, 19, and 23. These numbers are only divisible by 1 and themselves, which defines them as prime.
19 of them.
There are 19 integers between 1 and 100 containing a 5.
The first 3 digit number divisible by 19 is 114 (= 19 x 6) The last 3 digit number divisible by 19 is 988 (= 19 x 52) That means that there are 52 - 6 + 1 = 47 three digit numbers that are divisible by 19.
The number 836 is divisible by several integers. It is divisible by 1, 2, 4, 11, 19, 28, 38, 83, 139, and 418, as well as 836 itself. The prime factorization of 836 is 2² × 11 × 19, which helps identify its divisors.
