Given numbers are 720, 309, 959, 906

The list of prime factors of all numbers are

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

Prime factors of 309 are 3 x 103

Prime factors of 959 are 7 x 137

Prime factors of 906 are 2 x 3 x 151

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

Given numbers are 720, 309, 959, 906

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

Apply this formula for all numbers.

Step1:

LCM(720, 309) = 74160

GCD(720, 309) = ( 720 x 309 ) / 74160

= 720 / 309

= 720

Step2:

LCM(3, 959) = 2877

GCD(3, 959) = ( 3 x 959 ) / 2877

= 3 / 959

= 3

Step3:

LCM(1, 906) = 906

GCD(1, 906) = ( 1 x 906 ) / 906

= 1 / 906

= 1

So, Greatest Common Divisor of 720, 309, 959, 906 is 1
