Given numbers are 712, 770, 891, 691

The list of prime factors of all numbers are

Prime factors of 712 are 2 x 2 x 2 x 89

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 891 are 3 x 3 x 3 x 3 x 11

Prime factors of 691 are 691

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

Given numbers are 712, 770, 891, 691

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

Apply this formula for all numbers.

Step1:

LCM(712, 770) = 274120

GCD(712, 770) = ( 712 x 770 ) / 274120

= 712 / 770

= 712

Step2:

LCM(2, 891) = 1782

GCD(2, 891) = ( 2 x 891 ) / 1782

= 2 / 891

= 2

Step3:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

So, Greatest Common Divisor of 712, 770, 891, 691 is 1
