Given numbers are 138, 817, 272, 459

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

Apply this formula for all numbers.

Step1:

LCM(138, 817) = 112746

GCD(138, 817) = ( 138 x 817 ) / 112746

= 138 / 817

= 138

Step2:

LCM(1, 272) = 272

GCD(1, 272) = ( 1 x 272 ) / 272

= 1 / 272

= 1

Step3:

LCM(1, 459) = 459

GCD(1, 459) = ( 1 x 459 ) / 459

= 1 / 459

= 1

So, Greatest Common Divisor of 138, 817, 272, 459 is 1
