Therefore, GCD of numbers 751, 266, 21, 391 is 1

Given Input Data is 751, 266, 21, 391

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

Prime Factorization of 751 is 751

Prime Factorization of 266 is 2 x 7 x 19

Prime Factorization of 21 is 3 x 7

Prime Factorization of 391 is 17 x 23

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(751, 266) = 199766

GCD(751, 266) = ( 751 x 266 ) / 199766

GCD(751, 266) = 199766 / 199766

GCD(751, 266) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 21

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

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

GCD(1, 21) = 21 / 21

GCD(1, 21) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 391

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

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

GCD(1, 391) = 391 / 391

GCD(1, 391) = 1

GCD of 751, 266, 21, 391 is 1
