Therefore, GCD of numbers 938, 469, 15, 945 is 1

Given Input Data is 938, 469, 15, 945

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

Prime Factorization of 938 is 2 x 7 x 67

Prime Factorization of 469 is 7 x 67

Prime Factorization of 15 is 3 x 5

Prime Factorization of 945 is 3 x 3 x 3 x 5 x 7

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(938, 469) = 938

GCD(938, 469) = ( 938 x 469 ) / 938

GCD(938, 469) = 439922 / 938

GCD(938, 469) = 469

Step2:

Here we consider the GCD from the above i.e. 469 as first number and the next as 15

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

LCM(469, 15) = 7035

GCD(469, 15) = ( 469 x 15 ) / 7035

GCD(469, 15) = 7035 / 7035

GCD(469, 15) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 945

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

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

GCD(1, 945) = 945 / 945

GCD(1, 945) = 1

GCD of 938, 469, 15, 945 is 1
