Given numbers are 438, 517, 678, 811

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

Apply this formula for all numbers.

Step1:

LCM(438, 517) = 226446

GCD(438, 517) = ( 438 x 517 ) / 226446

= 438 / 517

= 438

Step2:

LCM(1, 678) = 678

GCD(1, 678) = ( 1 x 678 ) / 678

= 1 / 678

= 1

Step3:

LCM(1, 811) = 811

GCD(1, 811) = ( 1 x 811 ) / 811

= 1 / 811

= 1

So, Greatest Common Divisor of 438, 517, 678, 811 is 1
