Given numbers are 305, 660, 484, 858

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

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

Prime factors of 484 are 2 x 2 x 11 x 11

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 305, 660, 484, 858

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

Apply this formula for all numbers.

Step1:

LCM(305, 660) = 40260

GCD(305, 660) = ( 305 x 660 ) / 40260

= 305 / 660

= 305

Step2:

LCM(5, 484) = 2420

GCD(5, 484) = ( 5 x 484 ) / 2420

= 5 / 484

= 5

Step3:

LCM(1, 858) = 858

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

= 1 / 858

= 1

So, Greatest Common Divisor of 305, 660, 484, 858 is 1
