Given numbers are 405, 430, 786, 401

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 430 are 2 x 5 x 43

Prime factors of 786 are 2 x 3 x 131

Prime factors of 401 are 401

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

Given numbers are 405, 430, 786, 401

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

Apply this formula for all numbers.

Step1:

LCM(405, 430) = 34830

GCD(405, 430) = ( 405 x 430 ) / 34830

= 405 / 430

= 405

Step2:

LCM(5, 786) = 3930

GCD(5, 786) = ( 5 x 786 ) / 3930

= 5 / 786

= 5

Step3:

LCM(1, 401) = 401

GCD(1, 401) = ( 1 x 401 ) / 401

= 1 / 401

= 1

So, Greatest Common Divisor of 405, 430, 786, 401 is 1
