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

Apply this formula for all numbers.

Step1:

LCM(171, 549) = 10431

GCD(171, 549) = ( 171 x 549 ) / 10431

= 171 / 549

= 171

Step2:

LCM(9, 781) = 7029

GCD(9, 781) = ( 9 x 781 ) / 7029

= 9 / 781

= 9

So, Greatest Common Divisor of 171, 549, 781 is 1
