Given numbers are 626, 405, 13, 470

The list of prime factors of all numbers are

Prime factors of 626 are 2 x 313

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 13 are 13

Prime factors of 470 are 2 x 5 x 47

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

Given numbers are 626, 405, 13, 470

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

Apply this formula for all numbers.

Step1:

LCM(626, 405) = 253530

GCD(626, 405) = ( 626 x 405 ) / 253530

= 626 / 405

= 626

Step2:

LCM(1, 13) = 13

GCD(1, 13) = ( 1 x 13 ) / 13

= 1 / 13

= 1

Step3:

LCM(1, 470) = 470

GCD(1, 470) = ( 1 x 470 ) / 470

= 1 / 470

= 1

So, Greatest Common Divisor of 626, 405, 13, 470 is 1
