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

Apply this formula for all numbers.

Step1:

LCM(798, 494) = 10374

GCD(798, 494) = ( 798 x 494 ) / 10374

= 798 / 494

= 798

Step2:

LCM(38, 488) = 9272

GCD(38, 488) = ( 38 x 488 ) / 9272

= 38 / 488

= 38

Step3:

LCM(2, 690) = 690

GCD(2, 690) = ( 2 x 690 ) / 690

= 2 / 690

= 2

So, Greatest Common Divisor of 798, 494, 488, 690 is 2
