Prime factors of 438 are 2 x 3 x 73

Prime factors of 389 are 389

Prime factors of 659 are 659

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 810, 438, 389, 659

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

Apply this formula for all numbers.

Step1:

LCM(810, 438) = 59130

GCD(810, 438) = ( 810 x 438 ) / 59130

= 810 / 438

= 810

Step2:

LCM(6, 389) = 2334

GCD(6, 389) = ( 6 x 389 ) / 2334

= 6 / 389

= 6

Step3:

LCM(1, 659) = 659

GCD(1, 659) = ( 1 x 659 ) / 659

= 1 / 659

= 1

So, Greatest Common Divisor of 810, 438, 389, 659 is 1
