Given numbers are 805, 408, 85, 656

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 85 are 5 x 17

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

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

Given numbers are 805, 408, 85, 656

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

Apply this formula for all numbers.

Step1:

LCM(805, 408) = 328440

GCD(805, 408) = ( 805 x 408 ) / 328440

= 805 / 408

= 805

Step2:

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

= 1 / 85

= 1

Step3:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

So, Greatest Common Divisor of 805, 408, 85, 656 is 1
