Given Input Data is 938, 560, 68, 515

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 560 is 2 x 2 x 2 x 2 x 5 x 7

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 515 is 5 x 103

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, 560) = 37520

GCD(938, 560) = ( 938 x 560 ) / 37520

GCD(938, 560) = 525280 / 37520

GCD(938, 560) = 14

Step2:

Here we consider the GCD from the above i.e. 14 as first number and the next as 68

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

LCM(14, 68) = 476

GCD(14, 68) = ( 14 x 68 ) / 476

GCD(14, 68) = 952 / 476

GCD(14, 68) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 515

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

LCM(2, 515) = 1030

GCD(2, 515) = ( 2 x 515 ) / 1030

GCD(2, 515) = 1030 / 1030

GCD(2, 515) = 1

GCD of 938, 560, 68, 515 is 1
