Given numbers are 945, 813, 720, 790

The list of prime factors of all numbers are

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 813 are 3 x 271

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

Prime factors of 790 are 2 x 5 x 79

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

Given numbers are 945, 813, 720, 790

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

Apply this formula for all numbers.

Step1:

LCM(945, 813) = 256095

GCD(945, 813) = ( 945 x 813 ) / 256095

= 945 / 813

= 945

Step2:

LCM(3, 720) = 720

GCD(3, 720) = ( 3 x 720 ) / 720

= 3 / 720

= 3

Step3:

LCM(3, 790) = 2370

GCD(3, 790) = ( 3 x 790 ) / 2370

= 3 / 790

= 3

So, Greatest Common Divisor of 945, 813, 720, 790 is 1
