Given Input Data is 486, 948, 26, 781

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

Prime Factorization of 486 is 2 x 3 x 3 x 3 x 3 x 3

Prime Factorization of 948 is 2 x 2 x 3 x 79

Prime Factorization of 26 is 2 x 13

Prime Factorization of 781 is 11 x 71

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(486, 948) = 76788

GCD(486, 948) = ( 486 x 948 ) / 76788

GCD(486, 948) = 460728 / 76788

GCD(486, 948) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 26

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

LCM(6, 26) = 78

GCD(6, 26) = ( 6 x 26 ) / 78

GCD(6, 26) = 156 / 78

GCD(6, 26) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 781

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

LCM(2, 781) = 1562

GCD(2, 781) = ( 2 x 781 ) / 1562

GCD(2, 781) = 1562 / 1562

GCD(2, 781) = 1

GCD of 486, 948, 26, 781 is 1
