Given numbers are 793, 289, 640, 550

The list of prime factors of all numbers are

Prime factors of 793 are 13 x 61

Prime factors of 289 are 17 x 17

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 550 are 2 x 5 x 5 x 11

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

Given numbers are 793, 289, 640, 550

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

Apply this formula for all numbers.

Step1:

LCM(793, 289) = 229177

GCD(793, 289) = ( 793 x 289 ) / 229177

= 793 / 289

= 793

Step2:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

Step3:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

So, Greatest Common Divisor of 793, 289, 640, 550 is 1
