Given numbers are 615, 655, 771, 417

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 655 are 5 x 131

Prime factors of 771 are 3 x 257

Prime factors of 417 are 3 x 139

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

Given numbers are 615, 655, 771, 417

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

Apply this formula for all numbers.

Step1:

LCM(615, 655) = 80565

GCD(615, 655) = ( 615 x 655 ) / 80565

= 615 / 655

= 615

Step2:

LCM(5, 771) = 3855

GCD(5, 771) = ( 5 x 771 ) / 3855

= 5 / 771

= 5

Step3:

LCM(1, 417) = 417

GCD(1, 417) = ( 1 x 417 ) / 417

= 1 / 417

= 1

So, Greatest Common Divisor of 615, 655, 771, 417 is 1
