Given numbers are 686, 636, 629, 238

The list of prime factors of all numbers are

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

Prime factors of 636 are 2 x 2 x 3 x 53

Prime factors of 629 are 17 x 37

Prime factors of 238 are 2 x 7 x 17

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

Given numbers are 686, 636, 629, 238

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

Apply this formula for all numbers.

Step1:

LCM(686, 636) = 218148

GCD(686, 636) = ( 686 x 636 ) / 218148

= 686 / 636

= 686

Step2:

LCM(2, 629) = 1258

GCD(2, 629) = ( 2 x 629 ) / 1258

= 2 / 629

= 2

Step3:

LCM(1, 238) = 238

GCD(1, 238) = ( 1 x 238 ) / 238

= 1 / 238

= 1

So, Greatest Common Divisor of 686, 636, 629, 238 is 1
