Given numbers are 457, 258, 128

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

Apply this formula for all numbers.

Step1:

LCM(457, 258) = 117906

GCD(457, 258) = ( 457 x 258 ) / 117906

= 457 / 258

= 457

Step2:

LCM(1, 128) = 128

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

= 1 / 128

= 1

So, Greatest Common Divisor of 457, 258, 128 is 1
