Is there some function so I can find a common factor in multiple expressions?
For example: syms x y
a= 5*(x^4/y)
b= 27*(x^4/y)
=> x^4/y is a common factor.
The reason I'm asking this is that I have some very long expressions I need to sum up. In order to shorten some stuff I would like to extract common factors and assign them to some variable. Thankful for any help!
