Given numbers are 905, 270, 257, 889

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

Apply this formula for all numbers.

Step1:

LCM(905, 270) = 48870

GCD(905, 270) = ( 905 x 270 ) / 48870

= 905 / 270

= 905

Step2:

LCM(5, 257) = 1285

GCD(5, 257) = ( 5 x 257 ) / 1285

= 5 / 257

= 5

Step3:

LCM(1, 889) = 889

GCD(1, 889) = ( 1 x 889 ) / 889

= 1 / 889

= 1

So, Greatest Common Divisor of 905, 270, 257, 889 is 1
