Given numbers are 438, 369, 406, 905

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

Apply this formula for all numbers.

Step1:

LCM(438, 369) = 53874

GCD(438, 369) = ( 438 x 369 ) / 53874

= 438 / 369

= 438

Step2:

LCM(3, 406) = 1218

GCD(3, 406) = ( 3 x 406 ) / 1218

= 3 / 406

= 3

Step3:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

So, Greatest Common Divisor of 438, 369, 406, 905 is 1
