Given numbers are 805, 455, 706, 861

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 455 are 5 x 7 x 13

Prime factors of 706 are 2 x 353

Prime factors of 861 are 3 x 7 x 41

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

Given numbers are 805, 455, 706, 861

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

Apply this formula for all numbers.

Step1:

LCM(805, 455) = 10465

GCD(805, 455) = ( 805 x 455 ) / 10465

= 805 / 455

= 805

Step2:

LCM(35, 706) = 24710

GCD(35, 706) = ( 35 x 706 ) / 24710

= 35 / 706

= 35

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 805, 455, 706, 861 is 1
