Given numbers are 921, 243, 129, 242

The list of prime factors of all numbers are

Prime factors of 921 are 3 x 307

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

Prime factors of 129 are 3 x 43

Prime factors of 242 are 2 x 11 x 11

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

Given numbers are 921, 243, 129, 242

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

Apply this formula for all numbers.

Step1:

LCM(921, 243) = 74601

GCD(921, 243) = ( 921 x 243 ) / 74601

= 921 / 243

= 921

Step2:

LCM(3, 129) = 129

GCD(3, 129) = ( 3 x 129 ) / 129

= 3 / 129

= 3

Step3:

LCM(3, 242) = 726

GCD(3, 242) = ( 3 x 242 ) / 726

= 3 / 242

= 3

So, Greatest Common Divisor of 921, 243, 129, 242 is 1
