Question 1028465
I need to find the greatest common divisor of
the two numbers
{{{ 2250/18 = 125 }}}
{{{ 486/18 = 27 }}}
I think 18 is the GCD, and 
18 is the largest number of supplies to be put
into each group
----------------
There are 125 groups that each have 18 bottles of water
There are 27 groups that each have 18 cans of food
