Given numbers are 328, 688, 372, 405

The list of prime factors of all numbers are

Prime factors of 328 are 2 x 2 x 2 x 41

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 372 are 2 x 2 x 3 x 31

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

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

Given numbers are 328, 688, 372, 405

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

Apply this formula for all numbers.

Step1:

LCM(328, 688) = 28208

GCD(328, 688) = ( 328 x 688 ) / 28208

= 328 / 688

= 328

Step2:

LCM(8, 372) = 744

GCD(8, 372) = ( 8 x 372 ) / 744

= 8 / 372

= 8

Step3:

LCM(4, 405) = 1620

GCD(4, 405) = ( 4 x 405 ) / 1620

= 4 / 405

= 4

So, Greatest Common Divisor of 328, 688, 372, 405 is 1
