Given numbers are 198, 684, 405, 797

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

Apply this formula for all numbers.

Step1:

LCM(198, 684) = 7524

GCD(198, 684) = ( 198 x 684 ) / 7524

= 198 / 684

= 198

Step2:

LCM(18, 405) = 810

GCD(18, 405) = ( 18 x 405 ) / 810

= 18 / 405

= 18

Step3:

LCM(9, 797) = 7173

GCD(9, 797) = ( 9 x 797 ) / 7173

= 9 / 797

= 9

So, Greatest Common Divisor of 198, 684, 405, 797 is 1
