Therefore, GCD of numbers 789, 411, 128, 984 is 1

Given Input Data is 789, 411, 128, 984

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 789 is 3 x 263

Prime Factorization of 411 is 3 x 137

Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 984 is 2 x 2 x 2 x 3 x 41

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

Step1:

Let's calculate the GCD of first two numbers

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

LCM(789, 411) = 108093

GCD(789, 411) = ( 789 x 411 ) / 108093

GCD(789, 411) = 324279 / 108093

GCD(789, 411) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 128

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

LCM(3, 128) = 384

GCD(3, 128) = ( 3 x 128 ) / 384

GCD(3, 128) = 384 / 384

GCD(3, 128) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 984

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

LCM(1, 984) = 984

GCD(1, 984) = ( 1 x 984 ) / 984

GCD(1, 984) = 984 / 984

GCD(1, 984) = 1

GCD of 789, 411, 128, 984 is 1
