Given numbers are 405, 415, 307, 549

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 415 are 5 x 83

Prime factors of 307 are 307

Prime factors of 549 are 3 x 3 x 61

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

Given numbers are 405, 415, 307, 549

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

Apply this formula for all numbers.

Step1:

LCM(405, 415) = 33615

GCD(405, 415) = ( 405 x 415 ) / 33615

= 405 / 415

= 405

Step2:

LCM(5, 307) = 1535

GCD(5, 307) = ( 5 x 307 ) / 1535

= 5 / 307

= 5

Step3:

LCM(1, 549) = 549

GCD(1, 549) = ( 1 x 549 ) / 549

= 1 / 549

= 1

So, Greatest Common Divisor of 405, 415, 307, 549 is 1
