GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(873, 561) = 163251
GCD(873, 561) = ( 873 x 561 ) / 163251
= 873 / 561
= 873
Step2:
LCM(3, 558) = 558
GCD(3, 558) = ( 3 x 558 ) / 558
= 3 / 558
= 3
Step3:
LCM(3, 621) = 621
GCD(3, 621) = ( 3 x 621 ) / 621
= 3 / 621
= 3
So, Greatest Common Divisor of 873, 561, 558, 621 is 3
