Given numbers are 806, 155, 720, 256

The list of prime factors of all numbers are

Prime factors of 806 are 2 x 13 x 31

Prime factors of 155 are 5 x 31

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 256 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

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

Given numbers are 806, 155, 720, 256

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

Apply this formula for all numbers.

Step1:

LCM(806, 155) = 4030

GCD(806, 155) = ( 806 x 155 ) / 4030

= 806 / 155

= 806

Step2:

LCM(31, 720) = 22320

GCD(31, 720) = ( 31 x 720 ) / 22320

= 31 / 720

= 31

Step3:

LCM(1, 256) = 256

GCD(1, 256) = ( 1 x 256 ) / 256

= 1 / 256

= 1

So, Greatest Common Divisor of 806, 155, 720, 256 is 1
