Given numbers are 518, 561, 553, 197

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

Apply this formula for all numbers.

Step1:

LCM(518, 561) = 290598

GCD(518, 561) = ( 518 x 561 ) / 290598

= 518 / 561

= 518

Step2:

LCM(1, 553) = 553

GCD(1, 553) = ( 1 x 553 ) / 553

= 1 / 553

= 1

Step3:

LCM(1, 197) = 197

GCD(1, 197) = ( 1 x 197 ) / 197

= 1 / 197

= 1

So, Greatest Common Divisor of 518, 561, 553, 197 is 1
