Given numbers are 438, 388, 503

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

Apply this formula for all numbers.

Step1:

LCM(438, 388) = 84972

GCD(438, 388) = ( 438 x 388 ) / 84972

= 438 / 388

= 438

Step2:

LCM(2, 503) = 1006

GCD(2, 503) = ( 2 x 503 ) / 1006

= 2 / 503

= 2

So, Greatest Common Divisor of 438, 388, 503 is 1
