Given numbers are 830, 321, 858, 729

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 321 are 3 x 107

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

Prime factors of 729 are 3 x 3 x 3 x 3 x 3 x 3

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

Given numbers are 830, 321, 858, 729

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

Apply this formula for all numbers.

Step1:

LCM(830, 321) = 266430

GCD(830, 321) = ( 830 x 321 ) / 266430

= 830 / 321

= 830

Step2:

LCM(1, 858) = 858

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

= 1 / 858

= 1

Step3:

LCM(1, 729) = 729

GCD(1, 729) = ( 1 x 729 ) / 729

= 1 / 729

= 1

So, Greatest Common Divisor of 830, 321, 858, 729 is 1
