GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(912, 309) = 93936
GCD(912, 309) = ( 912 x 309 ) / 93936
= 912 / 309
= 912
Step2:
LCM(3, 609) = 609
GCD(3, 609) = ( 3 x 609 ) / 609
= 3 / 609
= 3
Step3:
LCM(3, 861) = 861
GCD(3, 861) = ( 3 x 861 ) / 861
= 3 / 861
= 3
So, Greatest Common Divisor of 912, 309, 609, 861 is 3
