Given numbers are 585, 207, 438, 805

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

Apply this formula for all numbers.

Step1:

LCM(585, 207) = 13455

GCD(585, 207) = ( 585 x 207 ) / 13455

= 585 / 207

= 585

Step2:

LCM(9, 438) = 1314

GCD(9, 438) = ( 9 x 438 ) / 1314

= 9 / 438

= 9

Step3:

LCM(3, 805) = 2415

GCD(3, 805) = ( 3 x 805 ) / 2415

= 3 / 805

= 3

So, Greatest Common Divisor of 585, 207, 438, 805 is 1
