The list of prime factors of all numbers are

Prime factors of 165 are 3 x 5 x 11

Prime factors of 523 are 523

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

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

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

Given numbers are 165, 523, 990, 770

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

Apply this formula for all numbers.

Step1:

LCM(165, 523) = 86295

GCD(165, 523) = ( 165 x 523 ) / 86295

= 165 / 523

= 165

Step2:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

Step3:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

So, Greatest Common Divisor of 165, 523, 990, 770 is 1
