Given numbers are 561, 549, 241, 797

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

Apply this formula for all numbers.

Step1:

LCM(561, 549) = 102663

GCD(561, 549) = ( 561 x 549 ) / 102663

= 561 / 549

= 561

Step2:

LCM(3, 241) = 723

GCD(3, 241) = ( 3 x 241 ) / 723

= 3 / 241

= 3

Step3:

LCM(1, 797) = 797

GCD(1, 797) = ( 1 x 797 ) / 797

= 1 / 797

= 1

So, Greatest Common Divisor of 561, 549, 241, 797 is 1
