Using this calculator, you may get GCD of several polynomials at a time. You may switch on details to display step-by-step solutions.
To calculate the greatest common divisor of several polynomials, calculate the GCD of the first two polynomials, then calculate the GCD of the third polynomial and the result obtained in the previous step, and so on until the last polynomial.
E.g, to solve GCD of 4 polynomials: f1,f2,f3,f4 we calculate:
