Given numbers are 798, 469, 490, 405

The list of prime factors of all numbers are

Prime factors of 798 are 2 x 3 x 7 x 19

Prime factors of 469 are 7 x 67

Prime factors of 490 are 2 x 5 x 7 x 7

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

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

Given numbers are 798, 469, 490, 405

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

Apply this formula for all numbers.

Step1:

LCM(798, 469) = 53466

GCD(798, 469) = ( 798 x 469 ) / 53466

= 798 / 469

= 798

Step2:

LCM(7, 490) = 490

GCD(7, 490) = ( 7 x 490 ) / 490

= 7 / 490

= 7

Step3:

LCM(7, 405) = 2835

GCD(7, 405) = ( 7 x 405 ) / 2835

= 7 / 405

= 7

So, Greatest Common Divisor of 798, 469, 490, 405 is 1
