The list of prime factors of all numbers are

Prime factors of 697 are 17 x 41

Prime factors of 518 are 2 x 7 x 37

Prime factors of 221 are 13 x 17

Prime factors of 634 are 2 x 317

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

Given numbers are 697, 518, 221, 634

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

Apply this formula for all numbers.

Step1:

LCM(697, 518) = 361046

GCD(697, 518) = ( 697 x 518 ) / 361046

= 697 / 518

= 697

Step2:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

Step3:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1

So, Greatest Common Divisor of 697, 518, 221, 634 is 1
