Given numbers are 688, 522, 426, 355

The list of prime factors of all numbers are

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 522 are 2 x 3 x 3 x 29

Prime factors of 426 are 2 x 3 x 71

Prime factors of 355 are 5 x 71

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

Given numbers are 688, 522, 426, 355

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

Apply this formula for all numbers.

Step1:

LCM(688, 522) = 179568

GCD(688, 522) = ( 688 x 522 ) / 179568

= 688 / 522

= 688

Step2:

LCM(2, 426) = 426

GCD(2, 426) = ( 2 x 426 ) / 426

= 2 / 426

= 2

Step3:

LCM(2, 355) = 710

GCD(2, 355) = ( 2 x 355 ) / 710

= 2 / 355

= 2

So, Greatest Common Divisor of 688, 522, 426, 355 is 1
