Given numbers are 788, 911, 180, 455

The list of prime factors of all numbers are

Prime factors of 788 are 2 x 2 x 197

Prime factors of 911 are 911

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 455 are 5 x 7 x 13

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

Given numbers are 788, 911, 180, 455

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

Apply this formula for all numbers.

Step1:

LCM(788, 911) = 717868

GCD(788, 911) = ( 788 x 911 ) / 717868

= 788 / 911

= 788

Step2:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 788, 911, 180, 455 is 1
