Given numbers are 338, 860, 555, 810

The list of prime factors of all numbers are

Prime factors of 338 are 2 x 13 x 13

Prime factors of 860 are 2 x 2 x 5 x 43

Prime factors of 555 are 3 x 5 x 37

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

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

Given numbers are 338, 860, 555, 810

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

Apply this formula for all numbers.

Step1:

LCM(338, 860) = 145340

GCD(338, 860) = ( 338 x 860 ) / 145340

= 338 / 860

= 338

Step2:

LCM(2, 555) = 1110

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

= 2 / 555

= 2

Step3:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 338, 860, 555, 810 is 1
