Given numbers are 309, 666, 905, 300

The list of prime factors of all numbers are

Prime factors of 309 are 3 x 103

Prime factors of 666 are 2 x 3 x 3 x 37

Prime factors of 905 are 5 x 181

Prime factors of 300 are 2 x 2 x 3 x 5 x 5

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

Given numbers are 309, 666, 905, 300

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

Apply this formula for all numbers.

Step1:

LCM(309, 666) = 68598

GCD(309, 666) = ( 309 x 666 ) / 68598

= 309 / 666

= 309

Step2:

LCM(3, 905) = 2715

GCD(3, 905) = ( 3 x 905 ) / 2715

= 3 / 905

= 3

Step3:

LCM(1, 300) = 300

GCD(1, 300) = ( 1 x 300 ) / 300

= 1 / 300

= 1

So, Greatest Common Divisor of 309, 666, 905, 300 is 1
