GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(939, 105) = 32865
GCD(939, 105) = ( 939 x 105 ) / 32865
= 939 / 105
= 939
Step2:
LCM(3, 774) = 774
GCD(3, 774) = ( 3 x 774 ) / 774
= 3 / 774
= 3
Step3:
LCM(3, 561) = 561
GCD(3, 561) = ( 3 x 561 ) / 561
= 3 / 561
= 3
So, Greatest Common Divisor of 939, 105, 774, 561 is 3
