Given numbers are 386, 830, 247, 681

The list of prime factors of all numbers are

Prime factors of 386 are 2 x 193

Prime factors of 830 are 2 x 5 x 83

Prime factors of 247 are 13 x 19

Prime factors of 681 are 3 x 227

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

Given numbers are 386, 830, 247, 681

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

Apply this formula for all numbers.

Step1:

LCM(386, 830) = 160190

GCD(386, 830) = ( 386 x 830 ) / 160190

= 386 / 830

= 386

Step2:

LCM(2, 247) = 494

GCD(2, 247) = ( 2 x 247 ) / 494

= 2 / 247

= 2

Step3:

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

= 1 / 681

= 1

So, Greatest Common Divisor of 386, 830, 247, 681 is 1
