The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 351 are 3 x 3 x 3 x 13

Prime factors of 538 are 2 x 269

Prime factors of 669 are 3 x 223

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

Given numbers are 981, 351, 538, 669

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

Apply this formula for all numbers.

Step1:

LCM(981, 351) = 38259

GCD(981, 351) = ( 981 x 351 ) / 38259

= 981 / 351

= 981

Step2:

LCM(9, 538) = 4842

GCD(9, 538) = ( 9 x 538 ) / 4842

= 9 / 538

= 9

Step3:

LCM(1, 669) = 669

GCD(1, 669) = ( 1 x 669 ) / 669

= 1 / 669

= 1

So, Greatest Common Divisor of 981, 351, 538, 669 is 1
