Given numbers are 683, 198, 830, 820

The list of prime factors of all numbers are

Prime factors of 683 are 683

Prime factors of 198 are 2 x 3 x 3 x 11

Prime factors of 830 are 2 x 5 x 83

Prime factors of 820 are 2 x 2 x 5 x 41

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

Given numbers are 683, 198, 830, 820

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

Apply this formula for all numbers.

Step1:

LCM(683, 198) = 135234

GCD(683, 198) = ( 683 x 198 ) / 135234

= 683 / 198

= 683

Step2:

LCM(1, 830) = 830

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

= 1 / 830

= 1

Step3:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 683, 198, 830, 820 is 1
