Given numbers are 549, 342, 209, 620

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

Apply this formula for all numbers.

Step1:

LCM(549, 342) = 20862

GCD(549, 342) = ( 549 x 342 ) / 20862

= 549 / 342

= 549

Step2:

LCM(9, 209) = 1881

GCD(9, 209) = ( 9 x 209 ) / 1881

= 9 / 209

= 9

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 549, 342, 209, 620 is 1
