Therefore, GCD of numbers 207, 630, 64, 814 is 1

Given Input Data is 207, 630, 64, 814

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

Prime Factorization of 207 is 3 x 3 x 23

Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7

Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 814 is 2 x 11 x 37

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(207, 630) = 14490

GCD(207, 630) = ( 207 x 630 ) / 14490

GCD(207, 630) = 130410 / 14490

GCD(207, 630) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 64

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

LCM(9, 64) = 576

GCD(9, 64) = ( 9 x 64 ) / 576

GCD(9, 64) = 576 / 576

GCD(9, 64) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 814

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

LCM(1, 814) = 814

GCD(1, 814) = ( 1 x 814 ) / 814

GCD(1, 814) = 814 / 814

GCD(1, 814) = 1

GCD of 207, 630, 64, 814 is 1
