Given numbers are 426, 746, 178, 455

The list of prime factors of all numbers are

Prime factors of 426 are 2 x 3 x 71

Prime factors of 746 are 2 x 373

Prime factors of 178 are 2 x 89

Prime factors of 455 are 5 x 7 x 13

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

Given numbers are 426, 746, 178, 455

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

Apply this formula for all numbers.

Step1:

LCM(426, 746) = 158898

GCD(426, 746) = ( 426 x 746 ) / 158898

= 426 / 746

= 426

Step2:

LCM(2, 178) = 178

GCD(2, 178) = ( 2 x 178 ) / 178

= 2 / 178

= 2

Step3:

LCM(2, 455) = 910

GCD(2, 455) = ( 2 x 455 ) / 910

= 2 / 455

= 2

So, Greatest Common Divisor of 426, 746, 178, 455 is 1
