Prime factors of 192 are 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 979, 686, 192, 420

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

Apply this formula for all numbers.

Step1:

LCM(979, 686) = 671594

GCD(979, 686) = ( 979 x 686 ) / 671594

= 979 / 686

= 979

Step2:

LCM(1, 192) = 192

GCD(1, 192) = ( 1 x 192 ) / 192

= 1 / 192

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 979, 686, 192, 420 is 1
