Given numbers are 395, 616, 640, 798

The list of prime factors of all numbers are

Prime factors of 395 are 5 x 79

Prime factors of 616 are 2 x 2 x 2 x 7 x 11

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 798 are 2 x 3 x 7 x 19

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

Given numbers are 395, 616, 640, 798

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

Apply this formula for all numbers.

Step1:

LCM(395, 616) = 243320

GCD(395, 616) = ( 395 x 616 ) / 243320

= 395 / 616

= 395

Step2:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

Step3:

LCM(1, 798) = 798

GCD(1, 798) = ( 1 x 798 ) / 798

= 1 / 798

= 1

So, Greatest Common Divisor of 395, 616, 640, 798 is 1
