Given numbers are 730, 814, 861, 805

The list of prime factors of all numbers are

Prime factors of 730 are 2 x 5 x 73

Prime factors of 814 are 2 x 11 x 37

Prime factors of 861 are 3 x 7 x 41

Prime factors of 805 are 5 x 7 x 23

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

Given numbers are 730, 814, 861, 805

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

Apply this formula for all numbers.

Step1:

LCM(730, 814) = 297110

GCD(730, 814) = ( 730 x 814 ) / 297110

= 730 / 814

= 730

Step2:

LCM(2, 861) = 1722

GCD(2, 861) = ( 2 x 861 ) / 1722

= 2 / 861

= 2

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 730, 814, 861, 805 is 1
