what is the number of zeroes at end of product of numbers between 1 to 100?

• An easier way to solve these kinds of problems is dividing the highest numbers to the powers of 5
  
  100/5=20
  100/25= 4
  20+4 = 24 Zeros

• 24 is right answr.

• for first hundred natural numbers,
  100/5=20
  20/5=4
  then answer is (20 +4)
  
  take another example
  for first two hundred natural numbers,
  200/5=40
  40/5=8
  8/5=1 (take round figure)
  then answer is (40+8+1)

• method to find no. of 0's at end first find all 2's nd 5's factor in those no.
  then no. of 0's at end will be equal to n. wher n= no of 2's factor or no. of 5's factors (which is less).
  ex.=4*8*5
  so 2's factor=5
  nd 5's factor=1
  so answr=1

• THE SOLUTION IS 31...
  b'cz while multiplying these numbers,we would come across with unit numbers 2*5 or 5*4,,where we get single zero in the unit place,during the multiplication between 1-9,11-19,so on...
  Then we get 2*10=20 zeros(except the multiplication of 10,20,30,....100)
  wen we multiplied the obtained answer with these 10,20,30,...100,,we will get 20+11=31 number of zeros...
