Given numbers are 209, 798, 973, 621

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

Apply this formula for all numbers.

Step1:

LCM(209, 798) = 8778

GCD(209, 798) = ( 209 x 798 ) / 8778

= 209 / 798

= 209

Step2:

LCM(19, 973) = 18487

GCD(19, 973) = ( 19 x 973 ) / 18487

= 19 / 973

= 19

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 209, 798, 973, 621 is 1
