GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(819, 648) = 58968
GCD(819, 648) = ( 819 x 648 ) / 58968
= 819 / 648
= 819
Step2:
LCM(9, 717) = 2151
GCD(9, 717) = ( 9 x 717 ) / 2151
= 9 / 717
= 9
Step3:
LCM(3, 313) = 939
GCD(3, 313) = ( 3 x 313 ) / 939
= 3 / 313
= 3
So, Greatest Common Divisor of 819, 648, 717, 313 is 1
