---------------
There are 2 terms. Look for common factors. Both have b, c & d, so factor that out.
=
Both terms still have bcd, so do it again.
=
And again
=
Now the 2nd term has no "c", so factor out bd
=
Only d is common to both now. Factor out d^2, save a step
=
----------------------------- That's all.
Doing it like that is tedious and time consuming. Here's a different approach:

The highest exponent of b is 4. Of c is 3, and of d is 6.
-->
Divide the 2 terms by that.
=
