Given numbers are 805, 791, 945, 454

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 791 are 7 x 113

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 454 are 2 x 227

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

Given numbers are 805, 791, 945, 454

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

Apply this formula for all numbers.

Step1:

LCM(805, 791) = 90965

GCD(805, 791) = ( 805 x 791 ) / 90965

= 805 / 791

= 805

Step2:

LCM(7, 945) = 945

GCD(7, 945) = ( 7 x 945 ) / 945

= 7 / 945

= 7

Step3:

LCM(7, 454) = 3178

GCD(7, 454) = ( 7 x 454 ) / 3178

= 7 / 454

= 7

So, Greatest Common Divisor of 805, 791, 945, 454 is 1
