00:01
So we're being asked to find the prime factorization of 2 ,160.
00:05
Well, to do this, we must first find the smallest prime number that goes into this number.
00:11
Well, because it's even, two will divide into it evenly.
00:14
So we're going to divide it by two.
00:16
In other words, we're going to cut it in half.
00:18
Well, half of this number would be 1 ,080.
00:22
So now we're going to do the same thing.
00:24
We need to figure out the smallest prime number that goes into 180.
00:28
Well, because it's even, two will go into it.
00:30
So now when we divide 1 ,080 by 2, we'll get 540.
00:36
And now the same thing.
00:38
We have to figure out the smallest prime number that goes into 540.
00:41
Well, because it's even, it will be 2 again.
00:44
Well, when we divide 2 into 540, we'll get 270.
00:50
Well, again, we have to find the smallest prime number that goes into 270, and that would also be 2 because it's an even number.
00:57
So now when we divide 270 by 2, we're going to get 1 ,000.
01:03
So now we have to find the smallest prime number that goes into 135...
