Given numbers are 820, 843, 845, 173
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 843) = 691260
GCD(820, 843) = ( 820 x 843 ) / 691260
= 820 / 843
= 820
Step2:
LCM(1, 845) = 845
GCD(1, 845) = ( 1 x 845 ) / 845
= 1 / 845
= 1
Step3:
LCM(1, 173) = 173
GCD(1, 173) = ( 1 x 173 ) / 173
= 1 / 173
= 1
So, Greatest Common Divisor of 820, 843, 845, 173 is 1
