Given numbers are 709, 257, 491, 430

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

Apply this formula for all numbers.

Step1:

LCM(709, 257) = 182213

GCD(709, 257) = ( 709 x 257 ) / 182213

= 709 / 257

= 709

Step2:

LCM(1, 491) = 491

GCD(1, 491) = ( 1 x 491 ) / 491

= 1 / 491

= 1

Step3:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1

So, Greatest Common Divisor of 709, 257, 491, 430 is 1
