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 473 are 11 x 43

Prime factors of 789 are 3 x 263

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

Given numbers are 615, 655, 473, 789

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, 473) = 2365

GCD(5, 473) = ( 5 x 473 ) / 2365

= 5 / 473

= 5

Step3:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

So, Greatest Common Divisor of 615, 655, 473, 789 is 1
