how to calculate the power of a given number in a factorial

<div dir="ltr" style="text-align: left;" trbidi="on"> Hi<br /> I am Prakash and am I here with my First magic maths tutorial .<br /> We will calculate the number of a digit in a given factorial number.<br /> like- number of 2's in 20! or number of 3's in 20!<br /> so lets start<br /> <br /> this is a very simple technique you just need to divide the number recursively or continuosly till we get 1 and then simply add all of them .<br /> we are providing a picture for that<br /> <div class="separator" style="clear: both; text-align: center;"> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiVVQ6SmRDcQHA9msxYpxsht3ocg9cvUhsuK-Sx0iTXh82aJ6gYtFa-G7G4BmMAJTqL-7HxRLI5ucVEv3B7td6ra_mvxvR0NpfeZHNrud3O56wJSufoKlhc-7-Ylaq1sq-gVOcwmvC_yHw/s1600/20!.png" style="margin-left: 1em; margin-right: 1em;"><br /></a></div> <table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody> <tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhfCU5FlZwZiD1uyA9SjPcZUUAr2hejdW42NxX2BZsGCUzIdxma7g14le9AFPzqH6GFxz71qB5awL0obpmSsuAw2oZorAm_mBwNmz46Xu8DJfxtmC__7LpCRnqn-2MZ_GWloU2Lk1OtZTo/s1600/20!.png" style="margin-left: auto; margin-right: auto;"><img border="0" height="244" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhfCU5FlZwZiD1uyA9SjPcZUUAr2hejdW42NxX2BZsGCUzIdxma7g14le9AFPzqH6GFxz71qB5awL0obpmSsuAw2oZorAm_mBwNmz46Xu8DJfxtmC__7LpCRnqn-2MZ_GWloU2Lk1OtZTo/s1600/20!.png" width="320" /></a></td></tr> <tr><td class="tr-caption" style="text-align: center;">picture for magic maths 1</td><td class="tr-caption" style="text-align: center;"><br /></td></tr> </tbody></table> for 2 we are adding 10+5+2+1=18<br /> for 3 we are adding 6+2<br /> your task to find for 5<br /> now let us see what if we are doing it for 10<br /> clearly we can take 5*2 as 10.<br /> now find the number of 2's and 5's in the number and then whichever is lower just that number of 10's will be available .<br /> like we get 5 2's and 6 5's so only five times we can multiply 2 with 5 . so 5 number of 10's will be available .<br /> have question ? use our comments box . <br /> <br /></div>
