Given numbers are 309, 240, 270, 623

The list of prime factors of all numbers are

Prime factors of 309 are 3 x 103

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

Prime factors of 623 are 7 x 89

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

Given numbers are 309, 240, 270, 623

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

Apply this formula for all numbers.

Step1:

LCM(309, 240) = 24720

GCD(309, 240) = ( 309 x 240 ) / 24720

= 309 / 240

= 309

Step2:

LCM(3, 270) = 270

GCD(3, 270) = ( 3 x 270 ) / 270

= 3 / 270

= 3

Step3:

LCM(3, 623) = 1869

GCD(3, 623) = ( 3 x 623 ) / 1869

= 3 / 623

= 3

So, Greatest Common Divisor of 309, 240, 270, 623 is 1
