Given numbers are 561, 638, 539, 426

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

Apply this formula for all numbers.

Step1:

LCM(561, 638) = 32538

GCD(561, 638) = ( 561 x 638 ) / 32538

= 561 / 638

= 561

Step2:

LCM(11, 539) = 539

GCD(11, 539) = ( 11 x 539 ) / 539

= 11 / 539

= 11

Step3:

LCM(11, 426) = 4686

GCD(11, 426) = ( 11 x 426 ) / 4686

= 11 / 426

= 11

So, Greatest Common Divisor of 561, 638, 539, 426 is 1
