The list of prime factors of all numbers are

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

Prime factors of 255 are 3 x 5 x 17

Prime factors of 451 are 11 x 41

Prime factors of 655 are 5 x 131

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

Given numbers are 686, 255, 451, 655

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

Apply this formula for all numbers.

Step1:

LCM(686, 255) = 174930

GCD(686, 255) = ( 686 x 255 ) / 174930

= 686 / 255

= 686

Step2:

LCM(1, 451) = 451

GCD(1, 451) = ( 1 x 451 ) / 451

= 1 / 451

= 1

Step3:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

So, Greatest Common Divisor of 686, 255, 451, 655 is 1
