Given Input Data is 644, 948, 362, 265

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

Prime Factorization of 644 is 2 x 2 x 7 x 23

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

Prime Factorization of 362 is 2 x 181

Prime Factorization of 265 is 5 x 53

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(644, 948) = 152628

GCD(644, 948) = ( 644 x 948 ) / 152628

GCD(644, 948) = 610512 / 152628

GCD(644, 948) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 362

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

LCM(4, 362) = 724

GCD(4, 362) = ( 4 x 362 ) / 724

GCD(4, 362) = 1448 / 724

GCD(4, 362) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 265

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

LCM(2, 265) = 530

GCD(2, 265) = ( 2 x 265 ) / 530

GCD(2, 265) = 530 / 530

GCD(2, 265) = 1

GCD of 644, 948, 362, 265 is 1
