Given numbers are 351, 858, 688, 470

The list of prime factors of all numbers are

Prime factors of 351 are 3 x 3 x 3 x 13

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

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 470 are 2 x 5 x 47

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

Given numbers are 351, 858, 688, 470

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

Apply this formula for all numbers.

Step1:

LCM(351, 858) = 7722

GCD(351, 858) = ( 351 x 858 ) / 7722

= 351 / 858

= 351

Step2:

LCM(39, 688) = 26832

GCD(39, 688) = ( 39 x 688 ) / 26832

= 39 / 688

= 39

Step3:

LCM(1, 470) = 470

GCD(1, 470) = ( 1 x 470 ) / 470

= 1 / 470

= 1

So, Greatest Common Divisor of 351, 858, 688, 470 is 1
