The integer 240 has several factors

The integer 240 has several factors:
First, factor 240 to obtain
240=(2 4)*(3 1) (5^1).
When choosing the factor, use x=2^ m
3 ^ n 5^k ;
And m, n, k each have 5 (m+1), 2 (n+1), 2 (k+1) kinds of selection methods, and they are independent of each other, so there are a total of 5
2*2=20 factors.
