Answer:
5n^3
Step-by-step explanation:
For this type of problem, you can do the numbers and the variables separately and then combine them at the end.
First, lets do the variables:
n^4 has the following factors: n^1, n^2, n^3, n^4
n^3 has the following factors: n^1, n^2, n^3
The greatest common factor is n^3
Now for the numbers.
5 has the following factors: 1,5
30 has the following factors: 1,2,3,5,6,10,15,30
The greatest common factor is 5
Put it all together and the answer is 5n^3
