Given numbers are 418, 556, 997, 810

The list of prime factors of all numbers are

Prime factors of 418 are 2 x 11 x 19

Prime factors of 556 are 2 x 2 x 139

Prime factors of 997 are 997

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 418, 556, 997, 810

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

Apply this formula for all numbers.

Step1:

LCM(418, 556) = 116204

GCD(418, 556) = ( 418 x 556 ) / 116204

= 418 / 556

= 418

Step2:

LCM(2, 997) = 1994

GCD(2, 997) = ( 2 x 997 ) / 1994

= 2 / 997

= 2

Step3:

LCM(1, 810) = 810

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

= 1 / 810

= 1

So, Greatest Common Divisor of 418, 556, 997, 810 is 1
