Given numbers are 809, 803, 785, 408

The list of prime factors of all numbers are

Prime factors of 809 are 809

Prime factors of 803 are 11 x 73

Prime factors of 785 are 5 x 157

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

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

Given numbers are 809, 803, 785, 408

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

Apply this formula for all numbers.

Step1:

LCM(809, 803) = 649627

GCD(809, 803) = ( 809 x 803 ) / 649627

= 809 / 803

= 809

Step2:

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

= 1 / 785

= 1

Step3:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

So, Greatest Common Divisor of 809, 803, 785, 408 is 1
