Given numbers are 278, 200, 478, 393

The list of prime factors of all numbers are

Prime factors of 278 are 2 x 139

Prime factors of 200 are 2 x 2 x 2 x 5 x 5

Prime factors of 478 are 2 x 239

Prime factors of 393 are 3 x 131

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

Given numbers are 278, 200, 478, 393

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

Apply this formula for all numbers.

Step1:

LCM(278, 200) = 27800

GCD(278, 200) = ( 278 x 200 ) / 27800

= 278 / 200

= 278

Step2:

LCM(2, 478) = 478

GCD(2, 478) = ( 2 x 478 ) / 478

= 2 / 478

= 2

Step3:

LCM(2, 393) = 786

GCD(2, 393) = ( 2 x 393 ) / 786

= 2 / 393

= 2

So, Greatest Common Divisor of 278, 200, 478, 393 is 1
