Given numbers are 556, 689, 912, 121

The list of prime factors of all numbers are

Prime factors of 556 are 2 x 2 x 139

Prime factors of 689 are 13 x 53

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 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 556, 689, 912, 121

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

Apply this formula for all numbers.

Step1:

LCM(556, 689) = 383084

GCD(556, 689) = ( 556 x 689 ) / 383084

= 556 / 689

= 556

Step2:

LCM(1, 912) = 912

GCD(1, 912) = ( 1 x 912 ) / 912

= 1 / 912

= 1

Step3:

LCM(1, 121) = 121

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

= 1 / 121

= 1

So, Greatest Common Divisor of 556, 689, 912, 121 is 1
