Given numbers are 128, 309, 648, 311

The list of prime factors of all numbers are

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 309 are 3 x 103

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 311 are 311

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

Given numbers are 128, 309, 648, 311

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

Apply this formula for all numbers.

Step1:

LCM(128, 309) = 39552

GCD(128, 309) = ( 128 x 309 ) / 39552

= 128 / 309

= 128

Step2:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

Step3:

LCM(1, 311) = 311

GCD(1, 311) = ( 1 x 311 ) / 311

= 1 / 311

= 1

So, Greatest Common Divisor of 128, 309, 648, 311 is 1
