Given numbers are 851, 415, 809, 720

The list of prime factors of all numbers are

Prime factors of 851 are 23 x 37

Prime factors of 415 are 5 x 83

Prime factors of 809 are 809

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 851, 415, 809, 720

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

Apply this formula for all numbers.

Step1:

LCM(851, 415) = 353165

GCD(851, 415) = ( 851 x 415 ) / 353165

= 851 / 415

= 851

Step2:

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

= 1 / 809

= 1

Step3:

LCM(1, 720) = 720

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

= 1 / 720

= 1

So, Greatest Common Divisor of 851, 415, 809, 720 is 1
