Given numbers are 268, 403, 556, 121

The list of prime factors of all numbers are

Prime factors of 268 are 2 x 2 x 67

Prime factors of 403 are 13 x 31

Prime factors of 556 are 2 x 2 x 139

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 268, 403, 556, 121

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

Apply this formula for all numbers.

Step1:

LCM(268, 403) = 108004

GCD(268, 403) = ( 268 x 403 ) / 108004

= 268 / 403

= 268

Step2:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

Step3:

LCM(1, 121) = 121

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

= 1 / 121

= 1

So, Greatest Common Divisor of 268, 403, 556, 121 is 1
