Given numbers are 405, 612, 349, 842

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 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 349 are 349

Prime factors of 842 are 2 x 421

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

Given numbers are 405, 612, 349, 842

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

Apply this formula for all numbers.

Step1:

LCM(405, 612) = 27540

GCD(405, 612) = ( 405 x 612 ) / 27540

= 405 / 612

= 405

Step2:

LCM(9, 349) = 3141

GCD(9, 349) = ( 9 x 349 ) / 3141

= 9 / 349

= 9

Step3:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

So, Greatest Common Divisor of 405, 612, 349, 842 is 1
