- 2 and 5 are the only prime numbers that will give zero at the end when multiplied
therfore we get only 1 zero - 8 years agoHelpfull: Yes(4) No(0)
- Ans: 1
2*5*....... has 1 zero at the end - 8 years agoHelpfull: Yes(4) No(0)

- Prime no between 1 to 999999 are 2,3,5,7,11,13..........
Therefore when prod is taken then there is 5 and 2 in the series there for unit digit is always zero - 7 years agoHelpfull: Yes(2) No(0)
- for this we need combinations of 2*5, there are only one combination
so number of zeroes = 1 - 7 years agoHelpfull: Yes(1) No(0)

- 0 because no prime number can have zero at its end
- 8 years agoHelpfull: Yes(0) No(17)
- Just follow my trick :
We have to find remainder so just find multiple of 12 close to 45 ( whatever given in ques)
12*3=36
Therefore 45-36= 9 ans - 4 years agoHelpfull: Yes(0) No(0)
