The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 435 are 3 x 5 x 29

Prime factors of 634 are 2 x 317

Prime factors of 249 are 3 x 83

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

Given numbers are 981, 435, 634, 249

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

Apply this formula for all numbers.

Step1:

LCM(981, 435) = 142245

GCD(981, 435) = ( 981 x 435 ) / 142245

= 981 / 435

= 981

Step2:

LCM(3, 634) = 1902

GCD(3, 634) = ( 3 x 634 ) / 1902

= 3 / 634

= 3

Step3:

LCM(1, 249) = 249

GCD(1, 249) = ( 1 x 249 ) / 249

= 1 / 249

= 1

So, Greatest Common Divisor of 981, 435, 634, 249 is 1
