Therefore, GCD of numbers 253, 473, 26, 651 is 1

Given Input Data is 253, 473, 26, 651

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

Prime Factorization of 253 is 11 x 23

Prime Factorization of 473 is 11 x 43

Prime Factorization of 26 is 2 x 13

Prime Factorization of 651 is 3 x 7 x 31

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(253, 473) = 10879

GCD(253, 473) = ( 253 x 473 ) / 10879

GCD(253, 473) = 119669 / 10879

GCD(253, 473) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 26

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

LCM(11, 26) = 286

GCD(11, 26) = ( 11 x 26 ) / 286

GCD(11, 26) = 286 / 286

GCD(11, 26) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 651

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

LCM(1, 651) = 651

GCD(1, 651) = ( 1 x 651 ) / 651

GCD(1, 651) = 651 / 651

GCD(1, 651) = 1

GCD of 253, 473, 26, 651 is 1
