Given numbers are 438, 422, 405, 826

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

Apply this formula for all numbers.

Step1:

LCM(438, 422) = 92418

GCD(438, 422) = ( 438 x 422 ) / 92418

= 438 / 422

= 438

Step2:

LCM(2, 405) = 810

GCD(2, 405) = ( 2 x 405 ) / 810

= 2 / 405

= 2

Step3:

LCM(1, 826) = 826

GCD(1, 826) = ( 1 x 826 ) / 826

= 1 / 826

= 1

So, Greatest Common Divisor of 438, 422, 405, 826 is 1
