Given numbers are 988, 454, 498, 405

The list of prime factors of all numbers are

Prime factors of 988 are 2 x 2 x 13 x 19

Prime factors of 454 are 2 x 227

Prime factors of 498 are 2 x 3 x 83

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 988, 454, 498, 405

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

Apply this formula for all numbers.

Step1:

LCM(988, 454) = 224276

GCD(988, 454) = ( 988 x 454 ) / 224276

= 988 / 454

= 988

Step2:

LCM(2, 498) = 498

GCD(2, 498) = ( 2 x 498 ) / 498

= 2 / 498

= 2

Step3:

LCM(2, 405) = 810

GCD(2, 405) = ( 2 x 405 ) / 810

= 2 / 405

= 2

So, Greatest Common Divisor of 988, 454, 498, 405 is 1
