Given numbers are 780, 911, 663, 867

The list of prime factors of all numbers are

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 911 are 911

Prime factors of 663 are 3 x 13 x 17

Prime factors of 867 are 3 x 17 x 17

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

Given numbers are 780, 911, 663, 867

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

Apply this formula for all numbers.

Step1:

LCM(780, 911) = 710580

GCD(780, 911) = ( 780 x 911 ) / 710580

= 780 / 911

= 780

Step2:

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

= 1 / 663

= 1

Step3:

LCM(1, 867) = 867

GCD(1, 867) = ( 1 x 867 ) / 867

= 1 / 867

= 1

So, Greatest Common Divisor of 780, 911, 663, 867 is 1
