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

Apply this formula for all numbers.

Step1:

LCM(759, 144) = 36432

GCD(759, 144) = ( 759 x 144 ) / 36432

= 759 / 144

= 759

Step2:

LCM(3, 549) = 549

GCD(3, 549) = ( 3 x 549 ) / 549

= 3 / 549

= 3

Step3:

LCM(3, 621) = 621

GCD(3, 621) = ( 3 x 621 ) / 621

= 3 / 621

= 3

So, Greatest Common Divisor of 759, 144, 549, 621 is 3
