5) 392

- math -
**Marth**, Saturday, July 4, 2009 at 1:24pmKeep dividing by any factors until you get to the prime factors.

2 goes into 392.

392/2 = 196

2 goes into 196

196/2 = 98

2 goes into 98

98/2 = 49

So far we have 2^3, because we divided by 2 three times.

Now, 7 goes into 49.

49/7 = 7.

Therefore, we have 7^2 and 2^3 as the prime factors
