Given numbers are 805, 451, 390, 841

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 451 are 11 x 41

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 841 are 29 x 29

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

Given numbers are 805, 451, 390, 841

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

Apply this formula for all numbers.

Step1:

LCM(805, 451) = 363055

GCD(805, 451) = ( 805 x 451 ) / 363055

= 805 / 451

= 805

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 841) = 841

GCD(1, 841) = ( 1 x 841 ) / 841

= 1 / 841

= 1

So, Greatest Common Divisor of 805, 451, 390, 841 is 1
