Given numbers are 621, 432, 355, 384

The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 355 are 5 x 71

Prime factors of 384 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

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

Given numbers are 621, 432, 355, 384

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

Apply this formula for all numbers.

Step1:

LCM(621, 432) = 9936

GCD(621, 432) = ( 621 x 432 ) / 9936

= 621 / 432

= 621

Step2:

LCM(27, 355) = 9585

GCD(27, 355) = ( 27 x 355 ) / 9585

= 27 / 355

= 27

Step3:

LCM(1, 384) = 384

GCD(1, 384) = ( 1 x 384 ) / 384

= 1 / 384

= 1

So, Greatest Common Divisor of 621, 432, 355, 384 is 1
