Given numbers are 820, 405, 834, 449

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

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

Prime factors of 834 are 2 x 3 x 139

Prime factors of 449 are 449

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

Given numbers are 820, 405, 834, 449

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

Apply this formula for all numbers.

Step1:

LCM(820, 405) = 66420

GCD(820, 405) = ( 820 x 405 ) / 66420

= 820 / 405

= 820

Step2:

LCM(5, 834) = 4170

GCD(5, 834) = ( 5 x 834 ) / 4170

= 5 / 834

= 5

Step3:

LCM(1, 449) = 449

GCD(1, 449) = ( 1 x 449 ) / 449

= 1 / 449

= 1

So, Greatest Common Divisor of 820, 405, 834, 449 is 1
