Given numbers are 905, 309, 825, 486

The list of prime factors of all numbers are

Prime factors of 905 are 5 x 181

Prime factors of 309 are 3 x 103

Prime factors of 825 are 3 x 5 x 5 x 11

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

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

Given numbers are 905, 309, 825, 486

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

Apply this formula for all numbers.

Step1:

LCM(905, 309) = 279645

GCD(905, 309) = ( 905 x 309 ) / 279645

= 905 / 309

= 905

Step2:

LCM(1, 825) = 825

GCD(1, 825) = ( 1 x 825 ) / 825

= 1 / 825

= 1

Step3:

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

= 1 / 486

= 1

So, Greatest Common Divisor of 905, 309, 825, 486 is 1
