Given numbers are 139, 438, 553, 443

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

Apply this formula for all numbers.

Step1:

LCM(139, 438) = 60882

GCD(139, 438) = ( 139 x 438 ) / 60882

= 139 / 438

= 139

Step2:

LCM(1, 553) = 553

GCD(1, 553) = ( 1 x 553 ) / 553

= 1 / 553

= 1

Step3:

LCM(1, 443) = 443

GCD(1, 443) = ( 1 x 443 ) / 443

= 1 / 443

= 1

So, Greatest Common Divisor of 139, 438, 553, 443 is 1
