Given numbers are 821, 392, 499, 798

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

Apply this formula for all numbers.

Step1:

LCM(821, 392) = 321832

GCD(821, 392) = ( 821 x 392 ) / 321832

= 821 / 392

= 821

Step2:

LCM(1, 499) = 499

GCD(1, 499) = ( 1 x 499 ) / 499

= 1 / 499

= 1

Step3:

LCM(1, 798) = 798

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

= 1 / 798

= 1

So, Greatest Common Divisor of 821, 392, 499, 798 is 1
