Given numbers are 709, 728, 687, 809

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

Apply this formula for all numbers.

Step1:

LCM(709, 728) = 516152

GCD(709, 728) = ( 709 x 728 ) / 516152

= 709 / 728

= 709

Step2:

LCM(1, 687) = 687

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

= 1 / 687

= 1

Step3:

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

= 1 / 809

= 1

So, Greatest Common Divisor of 709, 728, 687, 809 is 1
