15*3 = 3*5*3 = 3*3*5
18*5 = 2*3*3*5 = 2*3*3*5
So GCF = numbers that appear in both lists (however many times in both) = 3*3*5 = 45
The product of 18 and 5 is 90
9x5 45x1 15x3
Use a calculator, it's 69....
90 18x5=90 15x6=90
-1/72x4 + c where c is the constant of integration.
The GCF of those two terms is 3x3
15x3+12x2
0,6x4=15x3
15x3 is equal to 45.
90
105x3
45
It is: 5x
