The Greatest Common Factor

The idea
The greatest common factor of polynomials is the largest polynomial that divides evenly into each of them.
In practice
For 12x³ and 18x², the GCF is 6x²: 6 is the largest shared coefficient factor, x² the largest shared power.
Where people slip
Take the smallest exponent on each shared variable.
