Given numbers are 320, 164, 91, 770

The list of prime factors of all numbers are

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 164 are 2 x 2 x 41

Prime factors of 91 are 7 x 13

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 320, 164, 91, 770

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

Apply this formula for all numbers.

Step1:

LCM(320, 164) = 13120

GCD(320, 164) = ( 320 x 164 ) / 13120

= 320 / 164

= 320

Step2:

LCM(4, 91) = 364

GCD(4, 91) = ( 4 x 91 ) / 364

= 4 / 91

= 4

Step3:

LCM(1, 770) = 770

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

= 1 / 770

= 1

So, Greatest Common Divisor of 320, 164, 91, 770 is 1
