Step-by-step explanation:

We have two numbers A and B and the greatest number which divide both A and B is greatest common factor of A and B. Now we have to find g.c.d of 720 and 810. Since for any number we can factories in its prime factors then, 720=2×2×2×2×3×3×5; 810=2×3×3×3×3×5 then greatest common factor is 2×3×3×5,then 90 divides 720 and 810.
