Given numbers are 921, 165, 973, 845
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(921, 165) = 50655
GCD(921, 165) = ( 921 x 165 ) / 50655
= 921 / 165
= 921
Step2:
LCM(3, 973) = 2919
GCD(3, 973) = ( 3 x 973 ) / 2919
= 3 / 973
= 3
Step3:
LCM(1, 845) = 845
GCD(1, 845) = ( 1 x 845 ) / 845
= 1 / 845
= 1
So, Greatest Common Divisor of 921, 165, 973, 845 is 1
