Therefore, GCD of numbers 260, 430, 921, 636 is 1

Given Input Data is 260, 430, 921, 636

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

Prime Factorization of 260 is 2 x 2 x 5 x 13

Prime Factorization of 430 is 2 x 5 x 43

Prime Factorization of 921 is 3 x 307

Prime Factorization of 636 is 2 x 2 x 3 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(260, 430) = 11180

GCD(260, 430) = ( 260 x 430 ) / 11180

GCD(260, 430) = 111800 / 11180

GCD(260, 430) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 921

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

LCM(10, 921) = 9210

GCD(10, 921) = ( 10 x 921 ) / 9210

GCD(10, 921) = 9210 / 9210

GCD(10, 921) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 636

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

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

GCD(1, 636) = 636 / 636

GCD(1, 636) = 1

GCD of 260, 430, 921, 636 is 1
