Given numbers are 405, 155, 194, 431

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 155 are 5 x 31

Prime factors of 194 are 2 x 97

Prime factors of 431 are 431

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

Given numbers are 405, 155, 194, 431

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

Apply this formula for all numbers.

Step1:

LCM(405, 155) = 12555

GCD(405, 155) = ( 405 x 155 ) / 12555

= 405 / 155

= 405

Step2:

LCM(5, 194) = 970

GCD(5, 194) = ( 5 x 194 ) / 970

= 5 / 194

= 5

Step3:

LCM(1, 431) = 431

GCD(1, 431) = ( 1 x 431 ) / 431

= 1 / 431

= 1

So, Greatest Common Divisor of 405, 155, 194, 431 is 1
