Given numbers are 686, 133, 106, 203

The list of prime factors of all numbers are

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

Prime factors of 133 are 7 x 19

Prime factors of 106 are 2 x 53

Prime factors of 203 are 7 x 29

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

Given numbers are 686, 133, 106, 203

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

Apply this formula for all numbers.

Step1:

LCM(686, 133) = 13034

GCD(686, 133) = ( 686 x 133 ) / 13034

= 686 / 133

= 686

Step2:

LCM(7, 106) = 742

GCD(7, 106) = ( 7 x 106 ) / 742

= 7 / 106

= 7

Step3:

LCM(1, 203) = 203

GCD(1, 203) = ( 1 x 203 ) / 203

= 1 / 203

= 1

So, Greatest Common Divisor of 686, 133, 106, 203 is 1
