Given numbers are 430, 425, 189, 654

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

Apply this formula for all numbers.

Step1:

LCM(430, 425) = 36550

GCD(430, 425) = ( 430 x 425 ) / 36550

= 430 / 425

= 430

Step2:

LCM(5, 189) = 945

GCD(5, 189) = ( 5 x 189 ) / 945

= 5 / 189

= 5

Step3:

LCM(1, 654) = 654

GCD(1, 654) = ( 1 x 654 ) / 654

= 1 / 654

= 1

So, Greatest Common Divisor of 430, 425, 189, 654 is 1
