GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(549, 873) = 53253
GCD(549, 873) = ( 549 x 873 ) / 53253
= 549 / 873
= 549
Step2:
LCM(9, 203) = 1827
GCD(9, 203) = ( 9 x 203 ) / 1827
= 9 / 203
= 9
Step3:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
So, Greatest Common Divisor of 549, 873, 203, 780 is 1
