How to find the most common numbers?

I have 300 number groups and each group has 22 different numbers (from 1 to 80).

Can I find the most common 5 or more numbers in these groups by excel, macro or any program?

for example, let us suppose that 4-15-23-36-45 are the most common numbers and these numbers are in 8 groups from 300.

Is it possible, I added my sample file, Thanks.
