Given numbers are 838, 430, 810, 555

The list of prime factors of all numbers are

Prime factors of 838 are 2 x 419

Prime factors of 430 are 2 x 5 x 43

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 555 are 3 x 5 x 37

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

Given numbers are 838, 430, 810, 555

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

Apply this formula for all numbers.

Step1:

LCM(838, 430) = 180170

GCD(838, 430) = ( 838 x 430 ) / 180170

= 838 / 430

= 838

Step2:

LCM(2, 810) = 810

GCD(2, 810) = ( 2 x 810 ) / 810

= 2 / 810

= 2

Step3:

LCM(2, 555) = 1110

GCD(2, 555) = ( 2 x 555 ) / 1110

= 2 / 555

= 2

So, Greatest Common Divisor of 838, 430, 810, 555 is 1
