Given numbers are 831, 720, 122, 629

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

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

Prime factors of 122 are 2 x 61

Prime factors of 629 are 17 x 37

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

Given numbers are 831, 720, 122, 629

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

Apply this formula for all numbers.

Step1:

LCM(831, 720) = 199440

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

= 831 / 720

= 831

Step2:

LCM(3, 122) = 366

GCD(3, 122) = ( 3 x 122 ) / 366

= 3 / 122

= 3

Step3:

LCM(1, 629) = 629

GCD(1, 629) = ( 1 x 629 ) / 629

= 1 / 629

= 1

So, Greatest Common Divisor of 831, 720, 122, 629 is 1
