Given numbers are 813, 408, 254, 554

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 254 are 2 x 127

Prime factors of 554 are 2 x 277

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

Given numbers are 813, 408, 254, 554

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

Apply this formula for all numbers.

Step1:

LCM(813, 408) = 110568

GCD(813, 408) = ( 813 x 408 ) / 110568

= 813 / 408

= 813

Step2:

LCM(3, 254) = 762

GCD(3, 254) = ( 3 x 254 ) / 762

= 3 / 254

= 3

Step3:

LCM(1, 554) = 554

GCD(1, 554) = ( 1 x 554 ) / 554

= 1 / 554

= 1

So, Greatest Common Divisor of 813, 408, 254, 554 is 1
