Given numbers are 720, 929, 391, 628

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 929 are 929

Prime factors of 391 are 17 x 23

Prime factors of 628 are 2 x 2 x 157

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

Given numbers are 720, 929, 391, 628

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

Apply this formula for all numbers.

Step1:

LCM(720, 929) = 668880

GCD(720, 929) = ( 720 x 929 ) / 668880

= 720 / 929

= 720

Step2:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

Step3:

LCM(1, 628) = 628

GCD(1, 628) = ( 1 x 628 ) / 628

= 1 / 628

= 1

So, Greatest Common Divisor of 720, 929, 391, 628 is 1
