You can use the division method or tree method.
DIVISION METHOD:
63 ... not divisible by 2, switch to 3
63 / 3 = 21
21 / 3 = 7
7 ... is prime so divide by itself and be done.
7 / 7 = 1
So the prime factors are 3 x 3 x 7
TREE METHOD:
.. 63
../ . \
3 ...21
...../ . \
....3 . 7
So the answer is 3 x 3 x 7
