Given numbers are 523, 605, 702, 638

The list of prime factors of all numbers are

Prime factors of 523 are 523

Prime factors of 605 are 5 x 11 x 11

Prime factors of 702 are 2 x 3 x 3 x 3 x 13

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 523, 605, 702, 638

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

Apply this formula for all numbers.

Step1:

LCM(523, 605) = 316415

GCD(523, 605) = ( 523 x 605 ) / 316415

= 523 / 605

= 523

Step2:

LCM(1, 702) = 702

GCD(1, 702) = ( 1 x 702 ) / 702

= 1 / 702

= 1

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 523, 605, 702, 638 is 1
