Given numbers are 638, 417, 166, 239

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

Apply this formula for all numbers.

Step1:

LCM(638, 417) = 266046

GCD(638, 417) = ( 638 x 417 ) / 266046

= 638 / 417

= 638

Step2:

LCM(1, 166) = 166

GCD(1, 166) = ( 1 x 166 ) / 166

= 1 / 166

= 1

Step3:

LCM(1, 239) = 239

GCD(1, 239) = ( 1 x 239 ) / 239

= 1 / 239

= 1

So, Greatest Common Divisor of 638, 417, 166, 239 is 1
