The list of prime factors of all numbers are

Prime factors of 278 are 2 x 139

Prime factors of 565 are 5 x 113

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 249 are 3 x 83

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

Given numbers are 278, 565, 550, 249

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

Apply this formula for all numbers.

Step1:

LCM(278, 565) = 157070

GCD(278, 565) = ( 278 x 565 ) / 157070

= 278 / 565

= 278

Step2:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

Step3:

LCM(1, 249) = 249

GCD(1, 249) = ( 1 x 249 ) / 249

= 1 / 249

= 1

So, Greatest Common Divisor of 278, 565, 550, 249 is 1
