The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 961 are 31 x 31

Prime factors of 561 are 3 x 11 x 17

Prime factors of 451 are 11 x 41

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

Given numbers are 805, 961, 561, 451

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

Apply this formula for all numbers.

Step1:

LCM(805, 961) = 773605

GCD(805, 961) = ( 805 x 961 ) / 773605

= 805 / 961

= 805

Step2:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

Step3:

LCM(1, 451) = 451

GCD(1, 451) = ( 1 x 451 ) / 451

= 1 / 451

= 1

So, Greatest Common Divisor of 805, 961, 561, 451 is 1
