Given numbers are 287, 342, 858, 384

The list of prime factors of all numbers are

Prime factors of 287 are 7 x 41

Prime factors of 342 are 2 x 3 x 3 x 19

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

Prime factors of 384 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

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

Given numbers are 287, 342, 858, 384

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

Apply this formula for all numbers.

Step1:

LCM(287, 342) = 98154

GCD(287, 342) = ( 287 x 342 ) / 98154

= 287 / 342

= 287

Step2:

LCM(1, 858) = 858

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

= 1 / 858

= 1

Step3:

LCM(1, 384) = 384

GCD(1, 384) = ( 1 x 384 ) / 384

= 1 / 384

= 1

So, Greatest Common Divisor of 287, 342, 858, 384 is 1
