FOR EXAMPLE The maximum power of 5 in 60!
Sol: 60! = 1 x 2 x 3 ..................60 so every fifth number is a multiple of 5. So there must be 60/5 = 12
In addition to this 25 and 50 contribute another two 5's. so total number is 12 + 2 = 14
Short cut: [605]+[6052]=12+2=14605605212214
Here [ ] Indicates greatest integer function.
