Given numbers are 430, 897, 455

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

Apply this formula for all numbers.

Step1:

LCM(430, 897) = 385710

GCD(430, 897) = ( 430 x 897 ) / 385710

= 430 / 897

= 430

Step2:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 430, 897, 455 is 1
