Given numbers are 405, 981, 852, 520

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 981 are 3 x 3 x 109

Prime factors of 852 are 2 x 2 x 3 x 71

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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

Given numbers are 405, 981, 852, 520

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

Apply this formula for all numbers.

Step1:

LCM(405, 981) = 44145

GCD(405, 981) = ( 405 x 981 ) / 44145

= 405 / 981

= 405

Step2:

LCM(9, 852) = 2556

GCD(9, 852) = ( 9 x 852 ) / 2556

= 9 / 852

= 9

Step3:

LCM(3, 520) = 1560

GCD(3, 520) = ( 3 x 520 ) / 1560

= 3 / 520

= 3

So, Greatest Common Divisor of 405, 981, 852, 520 is 1
