Given numbers are 819, 257, 466, 438

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

Apply this formula for all numbers.

Step1:

LCM(819, 257) = 210483

GCD(819, 257) = ( 819 x 257 ) / 210483

= 819 / 257

= 819

Step2:

LCM(1, 466) = 466

GCD(1, 466) = ( 1 x 466 ) / 466

= 1 / 466

= 1

Step3:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 819, 257, 466, 438 is 1
