The list of prime factors of all numbers are

Prime factors of 689 are 13 x 53

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 470 are 2 x 5 x 47

Prime factors of 771 are 3 x 257

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

Given numbers are 689, 550, 470, 771

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

Apply this formula for all numbers.

Step1:

LCM(689, 550) = 378950

GCD(689, 550) = ( 689 x 550 ) / 378950

= 689 / 550

= 689

Step2:

LCM(1, 470) = 470

GCD(1, 470) = ( 1 x 470 ) / 470

= 1 / 470

= 1

Step3:

LCM(1, 771) = 771

GCD(1, 771) = ( 1 x 771 ) / 771

= 1 / 771

= 1

So, Greatest Common Divisor of 689, 550, 470, 771 is 1
