The list of prime factors of all numbers are

Prime factors of 811 are 811

Prime factors of 430 are 2 x 5 x 43

Prime factors of 615 are 3 x 5 x 41

Prime factors of 515 are 5 x 103

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

Given numbers are 811, 430, 615, 515

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

Apply this formula for all numbers.

Step1:

LCM(811, 430) = 348730

GCD(811, 430) = ( 811 x 430 ) / 348730

= 811 / 430

= 811

Step2:

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

= 1 / 615

= 1

Step3:

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

= 1 / 515

= 1

So, Greatest Common Divisor of 811, 430, 615, 515 is 1
