The list of prime factors of all numbers are

Prime factors of 985 are 5 x 197

Prime factors of 345 are 3 x 5 x 23

Prime factors of 957 are 3 x 11 x 29

Prime factors of 161 are 7 x 23

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

Given numbers are 985, 345, 957, 161

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

Apply this formula for all numbers.

Step1:

LCM(985, 345) = 67965

GCD(985, 345) = ( 985 x 345 ) / 67965

= 985 / 345

= 985

Step2:

LCM(5, 957) = 4785

GCD(5, 957) = ( 5 x 957 ) / 4785

= 5 / 957

= 5

Step3:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

So, Greatest Common Divisor of 985, 345, 957, 161 is 1
