Given numbers are 306, 960, 643, 858

The list of prime factors of all numbers are

Prime factors of 306 are 2 x 3 x 3 x 17

Prime factors of 960 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 643 are 643

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 306, 960, 643, 858

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

Apply this formula for all numbers.

Step1:

LCM(306, 960) = 48960

GCD(306, 960) = ( 306 x 960 ) / 48960

= 306 / 960

= 306

Step2:

LCM(6, 643) = 3858

GCD(6, 643) = ( 6 x 643 ) / 3858

= 6 / 643

= 6

Step3:

LCM(1, 858) = 858

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

= 1 / 858

= 1

So, Greatest Common Divisor of 306, 960, 643, 858 is 1
