Given numbers are 405, 870, 334, 638

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 870 are 2 x 3 x 5 x 29

Prime factors of 334 are 2 x 167

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 405, 870, 334, 638

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

Apply this formula for all numbers.

Step1:

LCM(405, 870) = 23490

GCD(405, 870) = ( 405 x 870 ) / 23490

= 405 / 870

= 405

Step2:

LCM(15, 334) = 5010

GCD(15, 334) = ( 15 x 334 ) / 5010

= 15 / 334

= 15

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 405, 870, 334, 638 is 1
