Given numbers are 221, 910, 897, 555

The list of prime factors of all numbers are

Prime factors of 221 are 13 x 17

Prime factors of 910 are 2 x 5 x 7 x 13

Prime factors of 897 are 3 x 13 x 23

Prime factors of 555 are 3 x 5 x 37

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

Given numbers are 221, 910, 897, 555

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

Apply this formula for all numbers.

Step1:

LCM(221, 910) = 15470

GCD(221, 910) = ( 221 x 910 ) / 15470

= 221 / 910

= 221

Step2:

LCM(13, 897) = 897

GCD(13, 897) = ( 13 x 897 ) / 897

= 13 / 897

= 13

Step3:

LCM(13, 555) = 7215

GCD(13, 555) = ( 13 x 555 ) / 7215

= 13 / 555

= 13

So, Greatest Common Divisor of 221, 910, 897, 555 is 1
