Given numbers are 810, 805, 498, 945

The list of prime factors of all numbers are

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 805 are 5 x 7 x 23

Prime factors of 498 are 2 x 3 x 83

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 810, 805, 498, 945

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(810, 805) = 130410

GCD(810, 805) = ( 810 x 805 ) / 130410

= 810 / 805

= 810

Step2:

LCM(5, 498) = 2490

GCD(5, 498) = ( 5 x 498 ) / 2490

= 5 / 498

= 5

Step3:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

So, Greatest Common Divisor of 810, 805, 498, 945 is 1
