Find the number of zeroes in 58! (58 factorial)
Read Solution (Total 11)
-
- no. of zeroes in n! = [n/5]+[n/5^2]+[n/5^3]+...
number of zeroes in 58! = [58/5]+[58/5^2]+[58/5^3]= 11+2+0 = 13 - 10 years agoHelpfull: Yes(22) No(3)
- no of zeroes is
58/5=11
11/5=2
11+2=13
13 is answer
- 10 years agoHelpfull: Yes(18) No(0)
- 58/5+58/25=11+2=13
- 10 years agoHelpfull: Yes(2) No(0)
- 58/5+58/5^2
Taking quotient
11+2=13
So no.of zeros is 13 - 10 years agoHelpfull: Yes(0) No(0)
- [58/5]+[58/5^2]=11+2=13
13 zeroes exists in 58! - 10 years agoHelpfull: Yes(0) No(0)
- 58/5=11(quotient)
11/5=2
11+2=13(no.of zeros)
- 10 years agoHelpfull: Yes(0) No(0)
- 13 zeros
find out no of fives and no of two. - 10 years agoHelpfull: Yes(0) No(0)
- no of zeroes is
58/5=11
11/5=2
11+2=13
13 - 10 years agoHelpfull: Yes(0) No(0)
- 58/5 quotient is 11
11/5 quotient is 2
number of zeroes = 11+2 =13 - 10 years agoHelpfull: Yes(0) No(0)
- 13 since number of fives are 13 and 5 * even number will result in a zero.
Thus it has 13 zeroes. - 9 years agoHelpfull: Yes(0) No(0)
- 58/5+58/25=13. (add only the quotient)
- 8 years agoHelpfull: Yes(0) No(0)
