Answer:
171
Explanation:
First find the LCM of 14, 12 and 8
2 is a common factor for all three
14/2 = 7
12/2 = 6
8/2 = 4
We have 7 prime so we cannot factor further
The LCM is 7 x 6 x 4 = 168
Add 3 to 168 and that will be the smallest number that satisfies the requirement
168 + 3 = 171
171/14 : Quotient 12, remainder 3
171/12 : Quotient 14, remainder 3
171/8: Quotient 21, remainder 3
