Given numbers are 705, 830, 729, 912

The list of prime factors of all numbers are

Prime factors of 705 are 3 x 5 x 47

Prime factors of 830 are 2 x 5 x 83

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

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 x 19

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

Given numbers are 705, 830, 729, 912

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

Apply this formula for all numbers.

Step1:

LCM(705, 830) = 117030

GCD(705, 830) = ( 705 x 830 ) / 117030

= 705 / 830

= 705

Step2:

LCM(5, 729) = 3645

GCD(5, 729) = ( 5 x 729 ) / 3645

= 5 / 729

= 5

Step3:

LCM(1, 912) = 912

GCD(1, 912) = ( 1 x 912 ) / 912

= 1 / 912

= 1

So, Greatest Common Divisor of 705, 830, 729, 912 is 1
