Given numbers are 278, 738, 281, 478

The list of prime factors of all numbers are

Prime factors of 278 are 2 x 139

Prime factors of 738 are 2 x 3 x 3 x 41

Prime factors of 281 are 281

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, 738, 281, 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, 738) = 102582

GCD(278, 738) = ( 278 x 738 ) / 102582

= 278 / 738

= 278

Step2:

LCM(2, 281) = 562

GCD(2, 281) = ( 2 x 281 ) / 562

= 2 / 281

= 2

Step3:

LCM(1, 478) = 478

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

= 1 / 478

= 1

So, Greatest Common Divisor of 278, 738, 281, 478 is 1
