The remainder is 8 when 200 is divided by a positive integer 'x'. How many possible values of "x" are there ?
My efforts to solve this question:
I broke the number like this: 192 + 8. One thing that I concluded instantly is that 'x' will be larger than 8 since 8 is remainder. Now I have to find out all the factors of 192. The number of factors of 192 is 14. From 14, I subtracted common factors of 200 and 192. The number of common factors is 4(1,2,4,8). So the number of values that can divide 200 leaving remainder 8 is: 14-4=10.
I am not sure if I am conceptually correct.
The answer in the book is 8.
Please help me with concept.
Regards.
