Given numbers are 405, 411, 969, 812

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 411 are 3 x 137

Prime factors of 969 are 3 x 17 x 19

Prime factors of 812 are 2 x 2 x 7 x 29

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

Given numbers are 405, 411, 969, 812

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

Apply this formula for all numbers.

Step1:

LCM(405, 411) = 55485

GCD(405, 411) = ( 405 x 411 ) / 55485

= 405 / 411

= 405

Step2:

LCM(3, 969) = 969

GCD(3, 969) = ( 3 x 969 ) / 969

= 3 / 969

= 3

Step3:

LCM(3, 812) = 2436

GCD(3, 812) = ( 3 x 812 ) / 2436

= 3 / 812

= 3

So, Greatest Common Divisor of 405, 411, 969, 812 is 1
