Given numbers are 638, 302, 351, 662

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 302 are 2 x 151

Prime factors of 351 are 3 x 3 x 3 x 13

Prime factors of 662 are 2 x 331

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

Given numbers are 638, 302, 351, 662

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

Apply this formula for all numbers.

Step1:

LCM(638, 302) = 96338

GCD(638, 302) = ( 638 x 302 ) / 96338

= 638 / 302

= 638

Step2:

LCM(2, 351) = 702

GCD(2, 351) = ( 2 x 351 ) / 702

= 2 / 351

= 2

Step3:

LCM(1, 662) = 662

GCD(1, 662) = ( 1 x 662 ) / 662

= 1 / 662

= 1

So, Greatest Common Divisor of 638, 302, 351, 662 is 1
