Given numbers are 121, 381, 256, 550

The list of prime factors of all numbers are

Prime factors of 121 are 11 x 11

Prime factors of 381 are 3 x 127

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

Prime factors of 550 are 2 x 5 x 5 x 11

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

Given numbers are 121, 381, 256, 550

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

Apply this formula for all numbers.

Step1:

LCM(121, 381) = 46101

GCD(121, 381) = ( 121 x 381 ) / 46101

= 121 / 381

= 121

Step2:

LCM(1, 256) = 256

GCD(1, 256) = ( 1 x 256 ) / 256

= 1 / 256

= 1

Step3:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

So, Greatest Common Divisor of 121, 381, 256, 550 is 1
