9x9=81. Proving that one of the factor trees for 81 is 9xp.
441 / 252 = 1 r 189 252 / 189 = 1 r 63 189 / 63 = 3 r 0 The hcf of 441 and 252 is 63

It is: 22*32*7 = 252
252 Divide by two. 126,2 Divide by two. 63,2,2 Divide by three. 21,3,2,2 Divide by three. 7,3,3,2,2 Stop. All the factors are prime.
No, 2 is a factor of 252. 252 is a multiple of 2.
504 / \ 2 252 / \ 2 126 / \ 2 63 / \ 7 9 / \ 3 3 Sorry if that's a little hard to read, it's hard to make factor trees on the computer!
No because its largest even factor is itself 252
The greatest common factor of 252 and 300 is 12.
