Therefore, GCD of numbers 207, 747, 425, 160 is 1

Given Input Data is 207, 747, 425, 160

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

Prime Factorization of 207 is 3 x 3 x 23

Prime Factorization of 747 is 3 x 3 x 83

Prime Factorization of 425 is 5 x 5 x 17

Prime Factorization of 160 is 2 x 2 x 2 x 2 x 2 x 5

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(207, 747) = 17181

GCD(207, 747) = ( 207 x 747 ) / 17181

GCD(207, 747) = 154629 / 17181

GCD(207, 747) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 425

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

LCM(9, 425) = 3825

GCD(9, 425) = ( 9 x 425 ) / 3825

GCD(9, 425) = 3825 / 3825

GCD(9, 425) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 160

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

LCM(1, 160) = 160

GCD(1, 160) = ( 1 x 160 ) / 160

GCD(1, 160) = 160 / 160

GCD(1, 160) = 1

GCD of 207, 747, 425, 160 is 1
