Given numbers are 320, 810, 247, 782

The list of prime factors of all numbers are

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Prime factors of 247 are 13 x 19

Prime factors of 782 are 2 x 17 x 23

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

Given numbers are 320, 810, 247, 782

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

Apply this formula for all numbers.

Step1:

LCM(320, 810) = 25920

GCD(320, 810) = ( 320 x 810 ) / 25920

= 320 / 810

= 320

Step2:

LCM(10, 247) = 2470

GCD(10, 247) = ( 10 x 247 ) / 2470

= 10 / 247

= 10

Step3:

LCM(1, 782) = 782

GCD(1, 782) = ( 1 x 782 ) / 782

= 1 / 782

= 1

So, Greatest Common Divisor of 320, 810, 247, 782 is 1
