Given numbers are 278, 152, 720, 317

The list of prime factors of all numbers are

Prime factors of 278 are 2 x 139

Prime factors of 152 are 2 x 2 x 2 x 19

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 317 are 317

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

Given numbers are 278, 152, 720, 317

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

Apply this formula for all numbers.

Step1:

LCM(278, 152) = 21128

GCD(278, 152) = ( 278 x 152 ) / 21128

= 278 / 152

= 278

Step2:

LCM(2, 720) = 720

GCD(2, 720) = ( 2 x 720 ) / 720

= 2 / 720

= 2

Step3:

LCM(2, 317) = 634

GCD(2, 317) = ( 2 x 317 ) / 634

= 2 / 317

= 2

So, Greatest Common Divisor of 278, 152, 720, 317 is 1
