Given numbers are 691, 320, 858, 164

The list of prime factors of all numbers are

Prime factors of 691 are 691

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

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 164 are 2 x 2 x 41

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

Given numbers are 691, 320, 858, 164

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

Apply this formula for all numbers.

Step1:

LCM(691, 320) = 221120

GCD(691, 320) = ( 691 x 320 ) / 221120

= 691 / 320

= 691

Step2:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

Step3:

LCM(1, 164) = 164

GCD(1, 164) = ( 1 x 164 ) / 164

= 1 / 164

= 1

So, Greatest Common Divisor of 691, 320, 858, 164 is 1
