Given numbers are 117, 440, 205, 845

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

Apply this formula for all numbers.

Step1:

LCM(117, 440) = 51480

GCD(117, 440) = ( 117 x 440 ) / 51480

= 117 / 440

= 117

Step2:

LCM(1, 205) = 205

GCD(1, 205) = ( 1 x 205 ) / 205

= 1 / 205

= 1

Step3:

LCM(1, 845) = 845

GCD(1, 845) = ( 1 x 845 ) / 845

= 1 / 845

= 1

So, Greatest Common Divisor of 117, 440, 205, 845 is 1
