Given numbers are 786, 405, 778, 389

The list of prime factors of all numbers are

Prime factors of 786 are 2 x 3 x 131

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 778 are 2 x 389

Prime factors of 389 are 389

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

Given numbers are 786, 405, 778, 389

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

Apply this formula for all numbers.

Step1:

LCM(786, 405) = 106110

GCD(786, 405) = ( 786 x 405 ) / 106110

= 786 / 405

= 786

Step2:

LCM(3, 778) = 2334

GCD(3, 778) = ( 3 x 778 ) / 2334

= 3 / 778

= 3

Step3:

LCM(1, 389) = 389

GCD(1, 389) = ( 1 x 389 ) / 389

= 1 / 389

= 1

So, Greatest Common Divisor of 786, 405, 778, 389 is 1
