Given numbers are 638, 436, 658, 273

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

Apply this formula for all numbers.

Step1:

LCM(638, 436) = 139084

GCD(638, 436) = ( 638 x 436 ) / 139084

= 638 / 436

= 638

Step2:

LCM(2, 658) = 658

GCD(2, 658) = ( 2 x 658 ) / 658

= 2 / 658

= 2

Step3:

LCM(2, 273) = 546

GCD(2, 273) = ( 2 x 273 ) / 546

= 2 / 273

= 2

So, Greatest Common Divisor of 638, 436, 658, 273 is 1
