Given numbers are 785, 437, 173, 687

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

Apply this formula for all numbers.

Step1:

LCM(785, 437) = 343045

GCD(785, 437) = ( 785 x 437 ) / 343045

= 785 / 437

= 785

Step2:

LCM(1, 173) = 173

GCD(1, 173) = ( 1 x 173 ) / 173

= 1 / 173

= 1

Step3:

LCM(1, 687) = 687

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

= 1 / 687

= 1

So, Greatest Common Divisor of 785, 437, 173, 687 is 1
