Given numbers are 785, 855, 768, 904

The list of prime factors of all numbers are

Prime factors of 785 are 5 x 157

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 904 are 2 x 2 x 2 x 113

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

Given numbers are 785, 855, 768, 904

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

Apply this formula for all numbers.

Step1:

LCM(785, 855) = 134235

GCD(785, 855) = ( 785 x 855 ) / 134235

= 785 / 855

= 785

Step2:

LCM(5, 768) = 3840

GCD(5, 768) = ( 5 x 768 ) / 3840

= 5 / 768

= 5

Step3:

LCM(1, 904) = 904

GCD(1, 904) = ( 1 x 904 ) / 904

= 1 / 904

= 1

So, Greatest Common Divisor of 785, 855, 768, 904 is 1
