Therefore, GCD of numbers 775, 425, 45, 403 is 1

Given Input Data is 775, 425, 45, 403

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

Prime Factorization of 775 is 5 x 5 x 31

Prime Factorization of 425 is 5 x 5 x 17

Prime Factorization of 45 is 3 x 3 x 5

Prime Factorization of 403 is 13 x 31

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(775, 425) = 13175

GCD(775, 425) = ( 775 x 425 ) / 13175

GCD(775, 425) = 329375 / 13175

GCD(775, 425) = 25

Step2:

Here we consider the GCD from the above i.e. 25 as first number and the next as 45

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

LCM(25, 45) = 225

GCD(25, 45) = ( 25 x 45 ) / 225

GCD(25, 45) = 1125 / 225

GCD(25, 45) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 403

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

LCM(5, 403) = 2015

GCD(5, 403) = ( 5 x 403 ) / 2015

GCD(5, 403) = 2015 / 2015

GCD(5, 403) = 1

GCD of 775, 425, 45, 403 is 1
