Given numbers are 121, 978, 912, 454

The list of prime factors of all numbers are

Prime factors of 121 are 11 x 11

Prime factors of 978 are 2 x 3 x 163

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 x 19

Prime factors of 454 are 2 x 227

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

Given numbers are 121, 978, 912, 454

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

Apply this formula for all numbers.

Step1:

LCM(121, 978) = 118338

GCD(121, 978) = ( 121 x 978 ) / 118338

= 121 / 978

= 121

Step2:

LCM(1, 912) = 912

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

= 1 / 912

= 1

Step3:

LCM(1, 454) = 454

GCD(1, 454) = ( 1 x 454 ) / 454

= 1 / 454

= 1

So, Greatest Common Divisor of 121, 978, 912, 454 is 1
