Given numbers are 784, 720, 187, 789

The list of prime factors of all numbers are

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

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

Prime factors of 187 are 11 x 17

Prime factors of 789 are 3 x 263

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

Given numbers are 784, 720, 187, 789

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

Apply this formula for all numbers.

Step1:

LCM(784, 720) = 35280

GCD(784, 720) = ( 784 x 720 ) / 35280

= 784 / 720

= 784

Step2:

LCM(16, 187) = 2992

GCD(16, 187) = ( 16 x 187 ) / 2992

= 16 / 187

= 16

Step3:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

So, Greatest Common Divisor of 784, 720, 187, 789 is 1
