Given numbers are 686, 302, 126, 631

The list of prime factors of all numbers are

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

Prime factors of 302 are 2 x 151

Prime factors of 126 are 2 x 3 x 3 x 7

Prime factors of 631 are 631

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

Given numbers are 686, 302, 126, 631

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

Apply this formula for all numbers.

Step1:

LCM(686, 302) = 103586

GCD(686, 302) = ( 686 x 302 ) / 103586

= 686 / 302

= 686

Step2:

LCM(2, 126) = 126

GCD(2, 126) = ( 2 x 126 ) / 126

= 2 / 126

= 2

Step3:

LCM(2, 631) = 1262

GCD(2, 631) = ( 2 x 631 ) / 1262

= 2 / 631

= 2

So, Greatest Common Divisor of 686, 302, 126, 631 is 1
