Given numbers are 686, 344, 302, 381

The list of prime factors of all numbers are

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 344 are 2 x 2 x 2 x 43

Prime factors of 302 are 2 x 151

Prime factors of 381 are 3 x 127

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

Given numbers are 686, 344, 302, 381

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

Apply this formula for all numbers.

Step1:

LCM(686, 344) = 117992

GCD(686, 344) = ( 686 x 344 ) / 117992

= 686 / 344

= 686

Step2:

LCM(2, 302) = 302

GCD(2, 302) = ( 2 x 302 ) / 302

= 2 / 302

= 2

Step3:

LCM(2, 381) = 762

GCD(2, 381) = ( 2 x 381 ) / 762

= 2 / 381

= 2

So, Greatest Common Divisor of 686, 344, 302, 381 is 1
