Given numbers are 638, 418, 88, 224

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

Apply this formula for all numbers.

Step1:

LCM(638, 418) = 12122

GCD(638, 418) = ( 638 x 418 ) / 12122

= 638 / 418

= 638

Step2:

LCM(22, 88) = 88

GCD(22, 88) = ( 22 x 88 ) / 88

= 22 / 88

= 22

Step3:

LCM(22, 224) = 2464

GCD(22, 224) = ( 22 x 224 ) / 2464

= 22 / 224

= 22

So, Greatest Common Divisor of 638, 418, 88, 224 is 2
