Given numbers are 520, 481, 128, 122

The list of prime factors of all numbers are

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 481 are 13 x 37

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 122 are 2 x 61

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

Given numbers are 520, 481, 128, 122

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

Apply this formula for all numbers.

Step1:

LCM(520, 481) = 19240

GCD(520, 481) = ( 520 x 481 ) / 19240

= 520 / 481

= 520

Step2:

LCM(13, 128) = 1664

GCD(13, 128) = ( 13 x 128 ) / 1664

= 13 / 128

= 13

Step3:

LCM(1, 122) = 122

GCD(1, 122) = ( 1 x 122 ) / 122

= 1 / 122

= 1

So, Greatest Common Divisor of 520, 481, 128, 122 is 1
