How many consecutive zeros in factorial 2013?
Every multiple of 5 contributes one 0.Multiples of 52 = 25 contribute a second 0;Multiples of 53 = 125 contribute a third 0;Multiples of 54 = 625 contribute a fourth 0.This suggests there are 501 zeros.Every multiple of 5 contributes one 0.Multiples of 52 = 25 contribute a second 0;Multiples of 53 = 125 contribute a third 0;Multiples of 54 = 625 contribute a fourth 0.This suggests there are 501 zeros.Every multiple of 5 contributes one 0.Multiples of 52 = 25 contribute a second 0;Multiples of 53 = 125 contribute a third 0;Multiples of 54 = 625 contribute a fourth 0.This suggests there are 501 zeros.Every multiple of 5 contributes one 0.Multiples of 52 = 25 contribute a second 0;Multiples of 53 = 125 contribute a third 0;Multiples of 54 = 625 contribute a fourth 0.This suggests there are 501 zeros.
