Question

Given two positive integers, a and b, where a≥b, create a program in python 3 that uses Euclid's Algorithm to find the GCD. A nonpositive input will be marked as "invalid input."

Example: gcd of 1785 and 546

Step Equation Quotient and Remainder
0 1785=q0(546)+r01785=q0(546)+r0 q0=3;r0=147q0=3;r0=147
1 546=q1(147)+r1546=q1(147)+r1 q1=3;r1=105q1=3;r1=105
2 147=q2(105)+r2147=q2(105)+r2 q2=1;r2=42q2=1;r2=42
3 105=q3(42)+r3105=q3(42)+r3 q3=2;r3=21q3=2;r3=21
4 42=q4(21)+r442=q4(21)+r4 q4=2;r4=0q4=2;r4=0

The gcd of 1785 and 546 is 21.
