For all those guys like me who found this question difficult to understand,
here's the simple explanation i got after searching for decades.
1. Find LCM of the first array a.
2.Find GCD / HCF of the second array b.
3.Find all the multiples of LCM up to GCD, which divides the GCD evenly.
For Example:
Here, In the given sample Input, The LCM of array a would be 4 and the GCD of the array b would be 16.
Now, Find all Multiples of 4,(like 4,8,12,16,...) upto 16, such that, (16%multiple_of_4_here) should be 0.
Here,
16%4=0 -----> count=1 (suppose this variable.)
16%8=0 -----> count=2
16%12!=0 ---> count=2
16%16=0 ---> count=3.

Thus, The answer is 3. Hope this helped you.
Thank you for your awesome explanation, it certainly helped me!
