Given numbers are 438, 635, 305, 297

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 635 are 5 x 127

Prime factors of 305 are 5 x 61

Prime factors of 297 are 3 x 3 x 3 x 11

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

Given numbers are 438, 635, 305, 297

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

Apply this formula for all numbers.

Step1:

LCM(438, 635) = 278130

GCD(438, 635) = ( 438 x 635 ) / 278130

= 438 / 635

= 438

Step2:

LCM(1, 305) = 305

GCD(1, 305) = ( 1 x 305 ) / 305

= 1 / 305

= 1

Step3:

LCM(1, 297) = 297

GCD(1, 297) = ( 1 x 297 ) / 297

= 1 / 297

= 1

So, Greatest Common Divisor of 438, 635, 305, 297 is 1
