Given numbers are 438, 256, 738, 263

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

Apply this formula for all numbers.

Step1:

LCM(438, 256) = 56064

GCD(438, 256) = ( 438 x 256 ) / 56064

= 438 / 256

= 438

Step2:

LCM(2, 738) = 738

GCD(2, 738) = ( 2 x 738 ) / 738

= 2 / 738

= 2

Step3:

LCM(2, 263) = 526

GCD(2, 263) = ( 2 x 263 ) / 526

= 2 / 263

= 2

So, Greatest Common Divisor of 438, 256, 738, 263 is 1
