Given numbers are 498, 490, 392, 819

The list of prime factors of all numbers are

Prime factors of 498 are 2 x 3 x 83

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

Prime factors of 819 are 3 x 3 x 7 x 13

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

Given numbers are 498, 490, 392, 819

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

Apply this formula for all numbers.

Step1:

LCM(498, 490) = 122010

GCD(498, 490) = ( 498 x 490 ) / 122010

= 498 / 490

= 498

Step2:

LCM(2, 392) = 392

GCD(2, 392) = ( 2 x 392 ) / 392

= 2 / 392

= 2

Step3:

LCM(2, 819) = 1638

GCD(2, 819) = ( 2 x 819 ) / 1638

= 2 / 819

= 2

So, Greatest Common Divisor of 498, 490, 392, 819 is 1
