Given numbers are 969, 805, 308, 405

The list of prime factors of all numbers are

Prime factors of 969 are 3 x 17 x 19

Prime factors of 805 are 5 x 7 x 23

Prime factors of 308 are 2 x 2 x 7 x 11

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 969, 805, 308, 405

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

Apply this formula for all numbers.

Step1:

LCM(969, 805) = 780045

GCD(969, 805) = ( 969 x 805 ) / 780045

= 969 / 805

= 969

Step2:

LCM(1, 308) = 308

GCD(1, 308) = ( 1 x 308 ) / 308

= 1 / 308

= 1

Step3:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

So, Greatest Common Divisor of 969, 805, 308, 405 is 1
