Given numbers are 480, 128, 969, 121

The list of prime factors of all numbers are

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

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

Prime factors of 969 are 3 x 17 x 19

Prime factors of 121 are 11 x 11

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

Given numbers are 480, 128, 969, 121

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

Apply this formula for all numbers.

Step1:

LCM(480, 128) = 1920

GCD(480, 128) = ( 480 x 128 ) / 1920

= 480 / 128

= 480

Step2:

LCM(32, 969) = 31008

GCD(32, 969) = ( 32 x 969 ) / 31008

= 32 / 969

= 32

Step3:

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

= 1 / 121

= 1

So, Greatest Common Divisor of 480, 128, 969, 121 is 1
