Given numbers are 615, 811, 680, 170

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 811 are 811

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 170 are 2 x 5 x 17

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

Given numbers are 615, 811, 680, 170

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

Apply this formula for all numbers.

Step1:

LCM(615, 811) = 498765

GCD(615, 811) = ( 615 x 811 ) / 498765

= 615 / 811

= 615

Step2:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

Step3:

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

= 1 / 170

= 1

So, Greatest Common Divisor of 615, 811, 680, 170 is 1
