Given numbers are 813, 112, 406, 684

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 112 are 2 x 2 x 2 x 2 x 7

Prime factors of 406 are 2 x 7 x 29

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

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

Given numbers are 813, 112, 406, 684

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

Apply this formula for all numbers.

Step1:

LCM(813, 112) = 91056

GCD(813, 112) = ( 813 x 112 ) / 91056

= 813 / 112

= 813

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

Step3:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

So, Greatest Common Divisor of 813, 112, 406, 684 is 1
