Given numbers are 221, 697, 855, 560

The list of prime factors of all numbers are

Prime factors of 221 are 13 x 17

Prime factors of 697 are 17 x 41

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

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

Given numbers are 221, 697, 855, 560

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

Apply this formula for all numbers.

Step1:

LCM(221, 697) = 9061

GCD(221, 697) = ( 221 x 697 ) / 9061

= 221 / 697

= 221

Step2:

LCM(17, 855) = 14535

GCD(17, 855) = ( 17 x 855 ) / 14535

= 17 / 855

= 17

Step3:

LCM(1, 560) = 560

GCD(1, 560) = ( 1 x 560 ) / 560

= 1 / 560

= 1

So, Greatest Common Divisor of 221, 697, 855, 560 is 1
