GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(684, 585) = 44460
GCD(684, 585) = ( 684 x 585 ) / 44460
= 684 / 585
= 684
Step2:
LCM(9, 885) = 2655
GCD(9, 885) = ( 9 x 885 ) / 2655
= 9 / 885
= 9
Step3:
LCM(3, 915) = 915
GCD(3, 915) = ( 3 x 915 ) / 915
= 3 / 915
= 3
So, Greatest Common Divisor of 684, 585, 885, 915 is 3
