**Anonymous**, Friday, December 16, 2011 at 10:59amThe first step is basically to factor 120175.

The obvious factor to do first is 5. this gives us 5 * 24035

Then factoring another 5 gives us 5 * 5 * 4807

Since 4807 obviously isn't divisible by 5 or 2, try 3.

So keep on trying the next biggest prime number (1,2,3,5,7,11,13,17...) turns out that 4807 is divisible by 11.

This gives us 5 * 5 * 11 * 437

Keep on going and you get

5 * 5 * 11 * 19 * 23

Just checking:

5 * 5 * 11 * 19 * 23 = 120175

Now converting these factors into letters.

You get the available letters EEKSW. this can be rearranged to be WEEKS.

However, remember that 5*5*11*19*23 can also be written as 25*11*19*23, since this also equals 120175.

This means the word could also have KSWY.

But you can't rearrange those letters to make a word.

So therefore the english word encoded as 120175 is WEEKS.

Basically, you factored the number, converted them into letters, and solved the anagram.
