Therefore, GCD of numbers 907, 399, 163, 646 is 1

Given Input Data is 907, 399, 163, 646

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

Prime Factorization of 907 is 907

Prime Factorization of 399 is 3 x 7 x 19

Prime Factorization of 163 is 163

Prime Factorization of 646 is 2 x 17 x 19

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(907, 399) = 361893

GCD(907, 399) = ( 907 x 399 ) / 361893

GCD(907, 399) = 361893 / 361893

GCD(907, 399) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 163

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

LCM(1, 163) = 163

GCD(1, 163) = ( 1 x 163 ) / 163

GCD(1, 163) = 163 / 163

GCD(1, 163) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 646

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

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

GCD(1, 646) = 646 / 646

GCD(1, 646) = 1

GCD of 907, 399, 163, 646 is 1
