Given numbers are 830, 399, 84, 351

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 399 are 3 x 7 x 19

Prime factors of 84 are 2 x 2 x 3 x 7

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

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

Given numbers are 830, 399, 84, 351

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

Apply this formula for all numbers.

Step1:

LCM(830, 399) = 331170

GCD(830, 399) = ( 830 x 399 ) / 331170

= 830 / 399

= 830

Step2:

LCM(1, 84) = 84

GCD(1, 84) = ( 1 x 84 ) / 84

= 1 / 84

= 1

Step3:

LCM(1, 351) = 351

GCD(1, 351) = ( 1 x 351 ) / 351

= 1 / 351

= 1

So, Greatest Common Divisor of 830, 399, 84, 351 is 1
