Given numbers are 640, 256, 161, 159

The list of prime factors of all numbers are

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Prime factors of 161 are 7 x 23

Prime factors of 159 are 3 x 53

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

Given numbers are 640, 256, 161, 159

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

Apply this formula for all numbers.

Step1:

LCM(640, 256) = 1280

GCD(640, 256) = ( 640 x 256 ) / 1280

= 640 / 256

= 640

Step2:

LCM(128, 161) = 20608

GCD(128, 161) = ( 128 x 161 ) / 20608

= 128 / 161

= 128

Step3:

LCM(1, 159) = 159

GCD(1, 159) = ( 1 x 159 ) / 159

= 1 / 159

= 1

So, Greatest Common Divisor of 640, 256, 161, 159 is 1
