Therefore, GCD of numbers 175, 820, 787, 943 is 1

Given Input Data is 175, 820, 787, 943

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

Prime Factorization of 175 is 5 x 5 x 7

Prime Factorization of 820 is 2 x 2 x 5 x 41

Prime Factorization of 787 is 787

Prime Factorization of 943 is 23 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(175, 820) = 28700

GCD(175, 820) = ( 175 x 820 ) / 28700

GCD(175, 820) = 143500 / 28700

GCD(175, 820) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 787

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

LCM(5, 787) = 3935

GCD(5, 787) = ( 5 x 787 ) / 3935

GCD(5, 787) = 3935 / 3935

GCD(5, 787) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 943

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

LCM(1, 943) = 943

GCD(1, 943) = ( 1 x 943 ) / 943

GCD(1, 943) = 943 / 943

GCD(1, 943) = 1

GCD of 175, 820, 787, 943 is 1
