Given numbers are 806, 180, 405, 136

The list of prime factors of all numbers are

Prime factors of 806 are 2 x 13 x 31

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 136 are 2 x 2 x 2 x 17

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

Given numbers are 806, 180, 405, 136

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

Apply this formula for all numbers.

Step1:

LCM(806, 180) = 72540

GCD(806, 180) = ( 806 x 180 ) / 72540

= 806 / 180

= 806

Step2:

LCM(2, 405) = 810

GCD(2, 405) = ( 2 x 405 ) / 810

= 2 / 405

= 2

Step3:

LCM(1, 136) = 136

GCD(1, 136) = ( 1 x 136 ) / 136

= 1 / 136

= 1

So, Greatest Common Divisor of 806, 180, 405, 136 is 1
