Given numbers are 615, 957, 855, 815

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 957 are 3 x 11 x 29

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 815 are 5 x 163

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

Given numbers are 615, 957, 855, 815

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

Apply this formula for all numbers.

Step1:

LCM(615, 957) = 196185

GCD(615, 957) = ( 615 x 957 ) / 196185

= 615 / 957

= 615

Step2:

LCM(3, 855) = 855

GCD(3, 855) = ( 3 x 855 ) / 855

= 3 / 855

= 3

Step3:

LCM(3, 815) = 2445

GCD(3, 815) = ( 3 x 815 ) / 2445

= 3 / 815

= 3

So, Greatest Common Divisor of 615, 957, 855, 815 is 1
