Given numbers are 395, 617, 680, 506

The list of prime factors of all numbers are

Prime factors of 395 are 5 x 79

Prime factors of 617 are 617

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

Prime factors of 506 are 2 x 11 x 23

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

Given numbers are 395, 617, 680, 506

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

Apply this formula for all numbers.

Step1:

LCM(395, 617) = 243715

GCD(395, 617) = ( 395 x 617 ) / 243715

= 395 / 617

= 395

Step2:

LCM(1, 680) = 680

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

= 1 / 680

= 1

Step3:

LCM(1, 506) = 506

GCD(1, 506) = ( 1 x 506 ) / 506

= 1 / 506

= 1

So, Greatest Common Divisor of 395, 617, 680, 506 is 1
