Given numbers are 811, 805, 609, 408

The list of prime factors of all numbers are

Prime factors of 811 are 811

Prime factors of 805 are 5 x 7 x 23

Prime factors of 609 are 3 x 7 x 29

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

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

Given numbers are 811, 805, 609, 408

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

Apply this formula for all numbers.

Step1:

LCM(811, 805) = 652855

GCD(811, 805) = ( 811 x 805 ) / 652855

= 811 / 805

= 811

Step2:

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

= 1 / 609

= 1

Step3:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

So, Greatest Common Divisor of 811, 805, 609, 408 is 1
