Given Input Data is 783, 319, 774, 278

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

Prime Factorization of 783 is 3 x 3 x 3 x 29

Prime Factorization of 319 is 11 x 29

Prime Factorization of 774 is 2 x 3 x 3 x 43

Prime Factorization of 278 is 2 x 139

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(783, 319) = 8613

GCD(783, 319) = ( 783 x 319 ) / 8613

GCD(783, 319) = 249777 / 8613

GCD(783, 319) = 29

Step2:

Here we consider the GCD from the above i.e. 29 as first number and the next as 774

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

LCM(29, 774) = 22446

GCD(29, 774) = ( 29 x 774 ) / 22446

GCD(29, 774) = 22446 / 22446

GCD(29, 774) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 278

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

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

GCD(1, 278) = 278 / 278

GCD(1, 278) = 1

GCD of 783, 319, 774, 278 is 1
