Given numbers are 785, 480, 664, 256

The list of prime factors of all numbers are

Prime factors of 785 are 5 x 157

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 664 are 2 x 2 x 2 x 83

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 785, 480, 664, 256

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

Apply this formula for all numbers.

Step1:

LCM(785, 480) = 75360

GCD(785, 480) = ( 785 x 480 ) / 75360

= 785 / 480

= 785

Step2:

LCM(5, 664) = 3320

GCD(5, 664) = ( 5 x 664 ) / 3320

= 5 / 664

= 5

Step3:

LCM(1, 256) = 256

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

= 1 / 256

= 1

So, Greatest Common Divisor of 785, 480, 664, 256 is 1
