Given numbers are 987, 320, 589, 805

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

Apply this formula for all numbers.

Step1:

LCM(987, 320) = 315840

GCD(987, 320) = ( 987 x 320 ) / 315840

= 987 / 320

= 987

Step2:

LCM(1, 589) = 589

GCD(1, 589) = ( 1 x 589 ) / 589

= 1 / 589

= 1

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 987, 320, 589, 805 is 1
