Given numbers are 438, 382, 103, 831

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

Apply this formula for all numbers.

Step1:

LCM(438, 382) = 83658

GCD(438, 382) = ( 438 x 382 ) / 83658

= 438 / 382

= 438

Step2:

LCM(2, 103) = 206

GCD(2, 103) = ( 2 x 103 ) / 206

= 2 / 103

= 2

Step3:

LCM(1, 831) = 831

GCD(1, 831) = ( 1 x 831 ) / 831

= 1 / 831

= 1

So, Greatest Common Divisor of 438, 382, 103, 831 is 1
