Given numbers are 638, 351, 361, 151

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

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

Prime factors of 361 are 19 x 19

Prime factors of 151 are 151

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

Given numbers are 638, 351, 361, 151

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

Apply this formula for all numbers.

Step1:

LCM(638, 351) = 223938

GCD(638, 351) = ( 638 x 351 ) / 223938

= 638 / 351

= 638

Step2:

LCM(1, 361) = 361

GCD(1, 361) = ( 1 x 361 ) / 361

= 1 / 361

= 1

Step3:

LCM(1, 151) = 151

GCD(1, 151) = ( 1 x 151 ) / 151

= 1 / 151

= 1

So, Greatest Common Divisor of 638, 351, 361, 151 is 1
