Given numbers are 807, 798, 390, 425

The list of prime factors of all numbers are

Prime factors of 807 are 3 x 269

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

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 425 are 5 x 5 x 17

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

Given numbers are 807, 798, 390, 425

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

Apply this formula for all numbers.

Step1:

LCM(807, 798) = 214662

GCD(807, 798) = ( 807 x 798 ) / 214662

= 807 / 798

= 807

Step2:

LCM(3, 390) = 390

GCD(3, 390) = ( 3 x 390 ) / 390

= 3 / 390

= 3

Step3:

LCM(3, 425) = 1275

GCD(3, 425) = ( 3 x 425 ) / 1275

= 3 / 425

= 3

So, Greatest Common Divisor of 807, 798, 390, 425 is 1
