Given Input Data is 550, 425, 79, 774

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

Prime Factorization of 550 is 2 x 5 x 5 x 11

Prime Factorization of 425 is 5 x 5 x 17

Prime Factorization of 79 is 79

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

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(550, 425) = 9350

GCD(550, 425) = ( 550 x 425 ) / 9350

GCD(550, 425) = 233750 / 9350

GCD(550, 425) = 25

Step2:

Here we consider the GCD from the above i.e. 25 as first number and the next as 79

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

LCM(25, 79) = 1975

GCD(25, 79) = ( 25 x 79 ) / 1975

GCD(25, 79) = 1975 / 1975

GCD(25, 79) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 774

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

LCM(1, 774) = 774

GCD(1, 774) = ( 1 x 774 ) / 774

GCD(1, 774) = 774 / 774

GCD(1, 774) = 1

GCD of 550, 425, 79, 774 is 1
