Given numbers are 691, 229, 720, 830

The list of prime factors of all numbers are

Prime factors of 691 are 691

Prime factors of 229 are 229

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 830 are 2 x 5 x 83

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

Given numbers are 691, 229, 720, 830

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

Apply this formula for all numbers.

Step1:

LCM(691, 229) = 158239

GCD(691, 229) = ( 691 x 229 ) / 158239

= 691 / 229

= 691

Step2:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

Step3:

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

= 1 / 830

= 1

So, Greatest Common Divisor of 691, 229, 720, 830 is 1
