oh wow i just did it out…nvm i figured that out…

i was making a really stupid mistake yesterday…i had 364 - 313 to be 61 instead of 51…
449 - 364 = 85…so i had 61 and 85 and couldn’t find any common factors…

i did it out today and saw 51 and 85 and it clicked automatically that it’s 17 that’s a common factor…then i did 221 / 17 = 13…so i figured out the answer to be 17

so i guess you could give me a 21/21 now too hahaha…
