Given numbers are 171, 164, 486, 858

The list of prime factors of all numbers are

Prime factors of 171 are 3 x 3 x 19

Prime factors of 164 are 2 x 2 x 41

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

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

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

Given numbers are 171, 164, 486, 858

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

Apply this formula for all numbers.

Step1:

LCM(171, 164) = 28044

GCD(171, 164) = ( 171 x 164 ) / 28044

= 171 / 164

= 171

Step2:

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

= 1 / 486

= 1

Step3:

LCM(1, 858) = 858

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

= 1 / 858

= 1

So, Greatest Common Divisor of 171, 164, 486, 858 is 1
