Given numbers are 351, 815, 702, 399

The list of prime factors of all numbers are

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

Prime factors of 815 are 5 x 163

Prime factors of 702 are 2 x 3 x 3 x 3 x 13

Prime factors of 399 are 3 x 7 x 19

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

Given numbers are 351, 815, 702, 399

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

Apply this formula for all numbers.

Step1:

LCM(351, 815) = 286065

GCD(351, 815) = ( 351 x 815 ) / 286065

= 351 / 815

= 351

Step2:

LCM(1, 702) = 702

GCD(1, 702) = ( 1 x 702 ) / 702

= 1 / 702

= 1

Step3:

LCM(1, 399) = 399

GCD(1, 399) = ( 1 x 399 ) / 399

= 1 / 399

= 1

So, Greatest Common Divisor of 351, 815, 702, 399 is 1
