Given numbers are 805, 720, 950, 644

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 950 are 2 x 5 x 5 x 19

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 805, 720, 950, 644

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

Apply this formula for all numbers.

Step1:

LCM(805, 720) = 115920

GCD(805, 720) = ( 805 x 720 ) / 115920

= 805 / 720

= 805

Step2:

LCM(5, 950) = 950

GCD(5, 950) = ( 5 x 950 ) / 950

= 5 / 950

= 5

Step3:

LCM(5, 644) = 3220

GCD(5, 644) = ( 5 x 644 ) / 3220

= 5 / 644

= 5

So, Greatest Common Divisor of 805, 720, 950, 644 is 1
