Given numbers are 355, 681, 324, 648

The list of prime factors of all numbers are

Prime factors of 355 are 5 x 71

Prime factors of 681 are 3 x 227

Prime factors of 324 are 2 x 2 x 3 x 3 x 3 x 3

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

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

Given numbers are 355, 681, 324, 648

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

Apply this formula for all numbers.

Step1:

LCM(355, 681) = 241755

GCD(355, 681) = ( 355 x 681 ) / 241755

= 355 / 681

= 355

Step2:

LCM(1, 324) = 324

GCD(1, 324) = ( 1 x 324 ) / 324

= 1 / 324

= 1

Step3:

LCM(1, 648) = 648

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

= 1 / 648

= 1

So, Greatest Common Divisor of 355, 681, 324, 648 is 1
