Given numbers are 689, 352, 386, 858

The list of prime factors of all numbers are

Prime factors of 689 are 13 x 53

Prime factors of 352 are 2 x 2 x 2 x 2 x 2 x 11

Prime factors of 386 are 2 x 193

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 689, 352, 386, 858

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

Apply this formula for all numbers.

Step1:

LCM(689, 352) = 242528

GCD(689, 352) = ( 689 x 352 ) / 242528

= 689 / 352

= 689

Step2:

LCM(1, 386) = 386

GCD(1, 386) = ( 1 x 386 ) / 386

= 1 / 386

= 1

Step3:

LCM(1, 858) = 858

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

= 1 / 858

= 1

So, Greatest Common Divisor of 689, 352, 386, 858 is 1
