The list of prime factors of all numbers are

Prime factors of 278 are 2 x 139

Prime factors of 356 are 2 x 2 x 89

Prime factors of 623 are 7 x 89

Prime factors of 478 are 2 x 239

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

Given numbers are 278, 356, 623, 478

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

Apply this formula for all numbers.

Step1:

LCM(278, 356) = 49484

GCD(278, 356) = ( 278 x 356 ) / 49484

= 278 / 356

= 278

Step2:

LCM(2, 623) = 1246

GCD(2, 623) = ( 2 x 623 ) / 1246

= 2 / 623

= 2

Step3:

LCM(1, 478) = 478

GCD(1, 478) = ( 1 x 478 ) / 478

= 1 / 478

= 1

So, Greatest Common Divisor of 278, 356, 623, 478 is 1
