The list of prime factors of all numbers are

Prime factors of 163 are 163

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Prime factors of 749 are 7 x 107

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

Given numbers are 163, 660, 858, 749

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

Apply this formula for all numbers.

Step1:

LCM(163, 660) = 107580

GCD(163, 660) = ( 163 x 660 ) / 107580

= 163 / 660

= 163

Step2:

LCM(1, 858) = 858

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

= 1 / 858

= 1

Step3:

LCM(1, 749) = 749

GCD(1, 749) = ( 1 x 749 ) / 749

= 1 / 749

= 1

So, Greatest Common Divisor of 163, 660, 858, 749 is 1
