Given numbers are 430, 845, 406, 128

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

Apply this formula for all numbers.

Step1:

LCM(430, 845) = 72670

GCD(430, 845) = ( 430 x 845 ) / 72670

= 430 / 845

= 430

Step2:

LCM(5, 406) = 2030

GCD(5, 406) = ( 5 x 406 ) / 2030

= 5 / 406

= 5

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 430, 845, 406, 128 is 1
