Given numbers are 278, 936, 285, 381

The list of prime factors of all numbers are

Prime factors of 278 are 2 x 139

Prime factors of 936 are 2 x 2 x 2 x 3 x 3 x 13

Prime factors of 285 are 3 x 5 x 19

Prime factors of 381 are 3 x 127

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

Given numbers are 278, 936, 285, 381

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

Apply this formula for all numbers.

Step1:

LCM(278, 936) = 130104

GCD(278, 936) = ( 278 x 936 ) / 130104

= 278 / 936

= 278

Step2:

LCM(2, 285) = 570

GCD(2, 285) = ( 2 x 285 ) / 570

= 2 / 285

= 2

Step3:

LCM(1, 381) = 381

GCD(1, 381) = ( 1 x 381 ) / 381

= 1 / 381

= 1

So, Greatest Common Divisor of 278, 936, 285, 381 is 1
