Given numbers are 585, 324, 989, 861

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(585, 324) = 21060

GCD(585, 324) = ( 585 x 324 ) / 21060

= 585 / 324

= 585

Step2:

LCM(9, 989) = 8901

GCD(9, 989) = ( 9 x 989 ) / 8901

= 9 / 989

= 9

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 585, 324, 989, 861 is 1
