Given numbers are 447, 122, 585, 989
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(447, 122) = 54534
GCD(447, 122) = ( 447 x 122 ) / 54534
= 447 / 122
= 447
Step2:
LCM(1, 585) = 585
GCD(1, 585) = ( 1 x 585 ) / 585
= 1 / 585
= 1
Step3:
LCM(1, 989) = 989
GCD(1, 989) = ( 1 x 989 ) / 989
= 1 / 989
= 1
So, Greatest Common Divisor of 447, 122, 585, 989 is 1
