Given numbers are 405, 870, 875, 531

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 875 are 5 x 5 x 5 x 7

Prime factors of 531 are 3 x 3 x 59

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

Given numbers are 405, 870, 875, 531

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, 875) = 2625

GCD(15, 875) = ( 15 x 875 ) / 2625

= 15 / 875

= 15

Step3:

LCM(5, 531) = 2655

GCD(5, 531) = ( 5 x 531 ) / 2655

= 5 / 531

= 5

So, Greatest Common Divisor of 405, 870, 875, 531 is 1
