The list of prime factors of all numbers are

Prime factors of 921 are 3 x 307

Prime factors of 399 are 3 x 7 x 19

Prime factors of 153 are 3 x 3 x 17

Prime factors of 538 are 2 x 269

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

Given numbers are 921, 399, 153, 538

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

Apply this formula for all numbers.

Step1:

LCM(921, 399) = 122493

GCD(921, 399) = ( 921 x 399 ) / 122493

= 921 / 399

= 921

Step2:

LCM(3, 153) = 153

GCD(3, 153) = ( 3 x 153 ) / 153

= 3 / 153

= 3

Step3:

LCM(3, 538) = 1614

GCD(3, 538) = ( 3 x 538 ) / 1614

= 3 / 538

= 3

So, Greatest Common Divisor of 921, 399, 153, 538 is 1
