Given numbers are 455, 634, 810, 426

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 634 are 2 x 317

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

Prime factors of 426 are 2 x 3 x 71

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

Given numbers are 455, 634, 810, 426

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

Apply this formula for all numbers.

Step1:

LCM(455, 634) = 288470

GCD(455, 634) = ( 455 x 634 ) / 288470

= 455 / 634

= 455

Step2:

LCM(1, 810) = 810

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

= 1 / 810

= 1

Step3:

LCM(1, 426) = 426

GCD(1, 426) = ( 1 x 426 ) / 426

= 1 / 426

= 1

So, Greatest Common Divisor of 455, 634, 810, 426 is 1
