Given numbers are 810, 578, 865, 730

The list of prime factors of all numbers are

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 578 are 2 x 17 x 17

Prime factors of 865 are 5 x 173

Prime factors of 730 are 2 x 5 x 73

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

Given numbers are 810, 578, 865, 730

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

Apply this formula for all numbers.

Step1:

LCM(810, 578) = 234090

GCD(810, 578) = ( 810 x 578 ) / 234090

= 810 / 578

= 810

Step2:

LCM(2, 865) = 1730

GCD(2, 865) = ( 2 x 865 ) / 1730

= 2 / 865

= 2

Step3:

LCM(1, 730) = 730

GCD(1, 730) = ( 1 x 730 ) / 730

= 1 / 730

= 1

So, Greatest Common Divisor of 810, 578, 865, 730 is 1
