441 is odd, so we can't divide it by 2.
Since the sum of its digits is 
, which is divisible by 3, we can divide 441 by 3, and we have
Which is still divisible by 3, because 
. We have
49 is not divisible by 3 anymore, nor by 5 (it doesn't end with 0 or 5).
It is divisible by 7 though, we have
and finally,
So, the factorization of 441 is
Yes you have the correct answers for each of the four problems. Nice work.
For anyone curious,
rd = removable discontinuity
id = infinite discontinuity
c = continuous
Multiplication it says time 3 so 12 times 3 is 36
