The list of prime factors of all numbers are

Prime factors of 578 are 2 x 17 x 17

Prime factors of 498 are 2 x 3 x 83

Prime factors of 778 are 2 x 389

Prime factors of 807 are 3 x 269

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

Given numbers are 578, 498, 778, 807

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

Apply this formula for all numbers.

Step1:

LCM(578, 498) = 143922

GCD(578, 498) = ( 578 x 498 ) / 143922

= 578 / 498

= 578

Step2:

LCM(2, 778) = 778

GCD(2, 778) = ( 2 x 778 ) / 778

= 2 / 778

= 2

Step3:

LCM(2, 807) = 1614

GCD(2, 807) = ( 2 x 807 ) / 1614

= 2 / 807

= 2

So, Greatest Common Divisor of 578, 498, 778, 807 is 1
