Given numbers are 309, 240, 620, 794

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 620 are 2 x 2 x 5 x 31

Prime factors of 794 are 2 x 397

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

Given numbers are 309, 240, 620, 794

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, 620) = 1860

GCD(3, 620) = ( 3 x 620 ) / 1860

= 3 / 620

= 3

Step3:

LCM(1, 794) = 794

GCD(1, 794) = ( 1 x 794 ) / 794

= 1 / 794

= 1

So, Greatest Common Divisor of 309, 240, 620, 794 is 1
