answer : 81.
2130 = 2*5*7*11*3
to experess this as a product of 3 factors let it be abc
2(only 1 digit & it it is to be counted 2 didits if it is 2^2) distributed to these 3 digits in [(1+3)C(3-1)]=3C2 ways = 3 ways
similary for 5,7,11,3 for each factor there will be 3 ways
hence total number of ways = 3*3*3*3*3= 243 ways.
Ans : 243 ways
