The list of prime factors of all numbers are

Prime factors of 957 are 3 x 11 x 29

Prime factors of 169 are 13 x 13

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

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

Given numbers are 957, 169, 690, 784

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

Apply this formula for all numbers.

Step1:

LCM(957, 169) = 161733

GCD(957, 169) = ( 957 x 169 ) / 161733

= 957 / 169

= 957

Step2:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

Step3:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

So, Greatest Common Divisor of 957, 169, 690, 784 is 1
