The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 169 are 13 x 13

Prime factors of 516 are 2 x 2 x 3 x 43

Prime factors of 921 are 3 x 307

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

Given numbers are 865, 169, 516, 921

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

Apply this formula for all numbers.

Step1:

LCM(865, 169) = 146185

GCD(865, 169) = ( 865 x 169 ) / 146185

= 865 / 169

= 865

Step2:

LCM(1, 516) = 516

GCD(1, 516) = ( 1 x 516 ) / 516

= 1 / 516

= 1

Step3:

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

= 1 / 921

= 1

So, Greatest Common Divisor of 865, 169, 516, 921 is 1
