can someone explain to me how to solve for the following:

Directions:Find the GCF of 6,18, and 30

well to get the answer you need to find the biggest comon factor that all of the numbers can evenly go into. like with 3, 6, 9 you would take 9 and write/type out several factors that 9 goes into, like, 18, 27, 36, 45, 54, 63, 72, 81 and then do the same thing with the other numbers until you find a number that all three numbers would go into evenly.
