100 to 999 is your range. there are 900 integers in this range. 450 are not divisble by 2 ( the odd ones). 600 are not divisble by 3. half of these are even so only an additional 300 integers are not divisble by 3 alone. so 450 & 300 =750
22 of them.
Of the 729 numbers that satisfy the requirement of positive integers, 104 are divisible by 7.
It is 19.
