Given numbers are 405, 620, 499, 349

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 620 are 2 x 2 x 5 x 31

Prime factors of 499 are 499

Prime factors of 349 are 349

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

Given numbers are 405, 620, 499, 349

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

Apply this formula for all numbers.

Step1:

LCM(405, 620) = 50220

GCD(405, 620) = ( 405 x 620 ) / 50220

= 405 / 620

= 405

Step2:

LCM(5, 499) = 2495

GCD(5, 499) = ( 5 x 499 ) / 2495

= 5 / 499

= 5

Step3:

LCM(1, 349) = 349

GCD(1, 349) = ( 1 x 349 ) / 349

= 1 / 349

= 1

So, Greatest Common Divisor of 405, 620, 499, 349 is 1
