Given numbers are 309, 143, 792, 720

The list of prime factors of all numbers are

Prime factors of 309 are 3 x 103

Prime factors of 143 are 11 x 13

Prime factors of 792 are 2 x 2 x 2 x 3 x 3 x 11

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 309, 143, 792, 720

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

Apply this formula for all numbers.

Step1:

LCM(309, 143) = 44187

GCD(309, 143) = ( 309 x 143 ) / 44187

= 309 / 143

= 309

Step2:

LCM(1, 792) = 792

GCD(1, 792) = ( 1 x 792 ) / 792

= 1 / 792

= 1

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 309, 143, 792, 720 is 1
