Given numbers are 709, 343, 65, 806

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

Apply this formula for all numbers.

Step1:

LCM(709, 343) = 243187

GCD(709, 343) = ( 709 x 343 ) / 243187

= 709 / 343

= 709

Step2:

LCM(1, 65) = 65

GCD(1, 65) = ( 1 x 65 ) / 65

= 1 / 65

= 1

Step3:

LCM(1, 806) = 806

GCD(1, 806) = ( 1 x 806 ) / 806

= 1 / 806

= 1

So, Greatest Common Divisor of 709, 343, 65, 806 is 1
