Given numbers are 765, 663, 364, 784

The list of prime factors of all numbers are

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 663 are 3 x 13 x 17

Prime factors of 364 are 2 x 2 x 7 x 13

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

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

Given numbers are 765, 663, 364, 784

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

Apply this formula for all numbers.

Step1:

LCM(765, 663) = 9945

GCD(765, 663) = ( 765 x 663 ) / 9945

= 765 / 663

= 765

Step2:

LCM(51, 364) = 18564

GCD(51, 364) = ( 51 x 364 ) / 18564

= 51 / 364

= 51

Step3:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

So, Greatest Common Divisor of 765, 663, 364, 784 is 1
