84 = 2^2*3*7
There are 3*2*2 = 12 factors.
If there are 20 linear factors, a1, a2, ..., a20, then the answer is 2^20. By the way, if they are a1^n1, a2^n2, ..., a20^n20, then the answer is (n1+1)(n2+1)...(n20+1).

try to use the factorization method, then count the total factors and surely it'll become 20!

There is no formula to find all of the numbers. You'll have to check each number and see if 84 is divisible by that number.

2,3,4 ,6,7,12,14,21,42 = 9 factors
