We're being asked to find the prime factorization of 432 using the latter method.
00:05
Well, to use this method, what we need to do first is find the smallest prime number that divides into 432 evenly.
00:12
Well, because it's an even number, 2 will do it into it.
00:15
So we're going to divide it by 2.
00:17
Well, when we divide 432 by 2, we get 216.
00:22
Now we're going to do the same thing.
00:24
What's the smallest prime number that divides into 216? well, it's even, so 2 will go into it.
00:29
Well, 216 divided by 2 is 108.
00:34
Same process.
00:36
The smallest prime number that goes into 108 is 2, and 108 divided by 2 is 54.
00:44
Same process, the smallest prime number that goes into 54 is 2, because it's even, and 54 divided by 2 is equal to 27.
00:53
So now what's the smallest prime number that goes into 27? well, that's going to be 3.
00:59
27 divided by 3 is 9.
01:00
And what's the smallest prime number that goes into nine? well, that's three...
