Given numbers are 945, 939, 608, 405

The list of prime factors of all numbers are

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 939 are 3 x 313

Prime factors of 608 are 2 x 2 x 2 x 2 x 2 x 19

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

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

Given numbers are 945, 939, 608, 405

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

Apply this formula for all numbers.

Step1:

LCM(945, 939) = 295785

GCD(945, 939) = ( 945 x 939 ) / 295785

= 945 / 939

= 945

Step2:

LCM(3, 608) = 1824

GCD(3, 608) = ( 3 x 608 ) / 1824

= 3 / 608

= 3

Step3:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

So, Greatest Common Divisor of 945, 939, 608, 405 is 1
