Given numbers are 426, 208, 525, 686

The list of prime factors of all numbers are

Prime factors of 426 are 2 x 3 x 71

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

Prime factors of 525 are 3 x 5 x 5 x 7

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

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

Given numbers are 426, 208, 525, 686

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

Apply this formula for all numbers.

Step1:

LCM(426, 208) = 44304

GCD(426, 208) = ( 426 x 208 ) / 44304

= 426 / 208

= 426

Step2:

LCM(2, 525) = 1050

GCD(2, 525) = ( 2 x 525 ) / 1050

= 2 / 525

= 2

Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

So, Greatest Common Divisor of 426, 208, 525, 686 is 1
