Given numbers are 605, 556, 810, 988

The list of prime factors of all numbers are

Prime factors of 605 are 5 x 11 x 11

Prime factors of 556 are 2 x 2 x 139

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

Prime factors of 988 are 2 x 2 x 13 x 19

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

Given numbers are 605, 556, 810, 988

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

Apply this formula for all numbers.

Step1:

LCM(605, 556) = 336380

GCD(605, 556) = ( 605 x 556 ) / 336380

= 605 / 556

= 605

Step2:

LCM(1, 810) = 810

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

= 1 / 810

= 1

Step3:

LCM(1, 988) = 988

GCD(1, 988) = ( 1 x 988 ) / 988

= 1 / 988

= 1

So, Greatest Common Divisor of 605, 556, 810, 988 is 1
