The GCF stands for greatest common factor. To represent a sum by its GCF we need to use the distributive property and we need to first find the GCF of the numbers. Let's break each number by its factors:
We now multiply the numbers that appear on both.
We now apply the distributive property:
To better understand the problem see the attached figure
we have
Multiply by 
both sides
Group terms that contain the same variable p and move the constant to the other side of the equation
25/20 × 100% = 125%
125% - 100% = 25%
25% profit :)
your answer would be
6 ways for 1st place
5 ways for 2nd place
4 ways for 3rd place
3 ways for fourth place
and in total there are 360 ways in total.
(6*5*4*3=360)
