Given numbers are 518, 701, 20, 128

The list of prime factors of all numbers are

Prime factors of 518 are 2 x 7 x 37

Prime factors of 701 are 701

Prime factors of 20 are 2 x 2 x 5

Prime factors of 128 are 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 518, 701, 20, 128

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

Apply this formula for all numbers.

Step1:

LCM(518, 701) = 363118

GCD(518, 701) = ( 518 x 701 ) / 363118

= 518 / 701

= 518

Step2:

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

= 1 / 20

= 1

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 518, 701, 20, 128 is 1
