The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 435 are 3 x 5 x 29

Prime factors of 170 are 2 x 5 x 17

Prime factors of 681 are 3 x 227

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

Given numbers are 655, 435, 170, 681

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

Apply this formula for all numbers.

Step1:

LCM(655, 435) = 56985

GCD(655, 435) = ( 655 x 435 ) / 56985

= 655 / 435

= 655

Step2:

LCM(5, 170) = 170

GCD(5, 170) = ( 5 x 170 ) / 170

= 5 / 170

= 5

Step3:

LCM(5, 681) = 3405

GCD(5, 681) = ( 5 x 681 ) / 3405

= 5 / 681

= 5

So, Greatest Common Divisor of 655, 435, 170, 681 is 1
