GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(819, 765) = 69615
GCD(819, 765) = ( 819 x 765 ) / 69615
= 819 / 765
= 819
Step2:
LCM(9, 325) = 2925
GCD(9, 325) = ( 9 x 325 ) / 2925
= 9 / 325
= 9
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 819, 765, 325, 689 is 1
