Given numbers are 121, 392, 324, 287

The list of prime factors of all numbers are

Prime factors of 121 are 11 x 11

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

Prime factors of 324 are 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 287 are 7 x 41

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

Given numbers are 121, 392, 324, 287

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

Apply this formula for all numbers.

Step1:

LCM(121, 392) = 47432

GCD(121, 392) = ( 121 x 392 ) / 47432

= 121 / 392

= 121

Step2:

LCM(1, 324) = 324

GCD(1, 324) = ( 1 x 324 ) / 324

= 1 / 324

= 1

Step3:

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

= 1 / 287

= 1

So, Greatest Common Divisor of 121, 392, 324, 287 is 1
