The list of prime factors of all numbers are

Prime factors of 898 are 2 x 449

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

Prime factors of 352 are 2 x 2 x 2 x 2 x 2 x 11

Prime factors of 391 are 17 x 23

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

Given numbers are 898, 720, 352, 391

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

Apply this formula for all numbers.

Step1:

LCM(898, 720) = 323280

GCD(898, 720) = ( 898 x 720 ) / 323280

= 898 / 720

= 898

Step2:

LCM(2, 352) = 352

GCD(2, 352) = ( 2 x 352 ) / 352

= 2 / 352

= 2

Step3:

LCM(2, 391) = 782

GCD(2, 391) = ( 2 x 391 ) / 782

= 2 / 391

= 2

So, Greatest Common Divisor of 898, 720, 352, 391 is 1
