Given Input Data is 693, 639, 544, 869

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

Prime Factorization of 693 is 3 x 3 x 7 x 11

Prime Factorization of 639 is 3 x 3 x 71

Prime Factorization of 544 is 2 x 2 x 2 x 2 x 2 x 17

Prime Factorization of 869 is 11 x 79

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(693, 639) = 49203

GCD(693, 639) = ( 693 x 639 ) / 49203

GCD(693, 639) = 442827 / 49203

GCD(693, 639) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 544

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

LCM(9, 544) = 4896

GCD(9, 544) = ( 9 x 544 ) / 4896

GCD(9, 544) = 4896 / 4896

GCD(9, 544) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 869

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

LCM(1, 869) = 869

GCD(1, 869) = ( 1 x 869 ) / 869

GCD(1, 869) = 869 / 869

GCD(1, 869) = 1

GCD of 693, 639, 544, 869 is 1
