The list of prime factors of all numbers are

Prime factors of 639 are 3 x 3 x 71

Prime factors of 336 are 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 915 are 3 x 5 x 61

Prime factors of 242 are 2 x 11 x 11

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

Given numbers are 639, 336, 915, 242

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

Apply this formula for all numbers.

Step1:

LCM(639, 336) = 71568

GCD(639, 336) = ( 639 x 336 ) / 71568

= 639 / 336

= 639

Step2:

LCM(3, 915) = 915

GCD(3, 915) = ( 3 x 915 ) / 915

= 3 / 915

= 3

Step3:

LCM(3, 242) = 726

GCD(3, 242) = ( 3 x 242 ) / 726

= 3 / 242

= 3

So, Greatest Common Divisor of 639, 336, 915, 242 is 1
