Given numbers are 720, 831, 643, 839

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 831 are 3 x 277

Prime factors of 643 are 643

Prime factors of 839 are 839

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

Given numbers are 720, 831, 643, 839

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

Apply this formula for all numbers.

Step1:

LCM(720, 831) = 199440

GCD(720, 831) = ( 720 x 831 ) / 199440

= 720 / 831

= 720

Step2:

LCM(3, 643) = 1929

GCD(3, 643) = ( 3 x 643 ) / 1929

= 3 / 643

= 3

Step3:

LCM(1, 839) = 839

GCD(1, 839) = ( 1 x 839 ) / 839

= 1 / 839

= 1

So, Greatest Common Divisor of 720, 831, 643, 839 is 1
