Given numbers are 405, 256, 43, 603

The list of prime factors of all numbers are

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

Prime factors of 256 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 43 are 43

Prime factors of 603 are 3 x 3 x 67

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

Given numbers are 405, 256, 43, 603

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

Apply this formula for all numbers.

Step1:

LCM(405, 256) = 103680

GCD(405, 256) = ( 405 x 256 ) / 103680

= 405 / 256

= 405

Step2:

LCM(1, 43) = 43

GCD(1, 43) = ( 1 x 43 ) / 43

= 1 / 43

= 1

Step3:

LCM(1, 603) = 603

GCD(1, 603) = ( 1 x 603 ) / 603

= 1 / 603

= 1

So, Greatest Common Divisor of 405, 256, 43, 603 is 1
