Given numbers are 805, 987, 117, 687

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

Apply this formula for all numbers.

Step1:

LCM(805, 987) = 113505

GCD(805, 987) = ( 805 x 987 ) / 113505

= 805 / 987

= 805

Step2:

LCM(7, 117) = 819

GCD(7, 117) = ( 7 x 117 ) / 819

= 7 / 117

= 7

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 805, 987, 117, 687 is 1
