Given numbers are 553, 980, 398, 793

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

Apply this formula for all numbers.

Step1:

LCM(553, 980) = 77420

GCD(553, 980) = ( 553 x 980 ) / 77420

= 553 / 980

= 553

Step2:

LCM(7, 398) = 2786

GCD(7, 398) = ( 7 x 398 ) / 2786

= 7 / 398

= 7

Step3:

LCM(1, 793) = 793

GCD(1, 793) = ( 1 x 793 ) / 793

= 1 / 793

= 1

So, Greatest Common Divisor of 553, 980, 398, 793 is 1
