Answer:
18
Step-by-step explanation:
This is because when you find the prime factors, you can take out the ones that they have together.
In this case:
9 - 3 * 3
6 - 3 * 2
2 - 2
So notice that each number has a maximum of 2 3s and 1 2, thus, you can multiple 3 * 3 * 2
I think its four
because 5x1=5
5x2=10
5x3=15
5x4=20
Step-by-step explanation:
6228 = 6000 + 200 + 20 + 8.
The 2s in 6228 represent 200 ; 20.
