Given numbers are 457, 305, 710, 789

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

Apply this formula for all numbers.

Step1:

LCM(457, 305) = 139385

GCD(457, 305) = ( 457 x 305 ) / 139385

= 457 / 305

= 457

Step2:

LCM(1, 710) = 710

GCD(1, 710) = ( 1 x 710 ) / 710

= 1 / 710

= 1

Step3:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

So, Greatest Common Divisor of 457, 305, 710, 789 is 1
