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 129 are 3 x 43

Prime factors of 539 are 7 x 7 x 11

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

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

Given numbers are 945, 129, 539, 168

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

Apply this formula for all numbers.

Step1:

LCM(945, 129) = 40635

GCD(945, 129) = ( 945 x 129 ) / 40635

= 945 / 129

= 945

Step2:

LCM(3, 539) = 1617

GCD(3, 539) = ( 3 x 539 ) / 1617

= 3 / 539

= 3

Step3:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

So, Greatest Common Divisor of 945, 129, 539, 168 is 1
