GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 684) = 74556
GCD(981, 684) = ( 981 x 684 ) / 74556
= 981 / 684
= 981
Step2:
LCM(9, 656) = 5904
GCD(9, 656) = ( 9 x 656 ) / 5904
= 9 / 656
= 9
Step3:
LCM(1, 306) = 306
GCD(1, 306) = ( 1 x 306 ) / 306
= 1 / 306
= 1
So, Greatest Common Divisor of 981, 684, 656, 306 is 1
