Therefore, GCD of numbers 551, 713, 26, 420 is 1

Given Input Data is 551, 713, 26, 420

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

Prime Factorization of 551 is 19 x 29

Prime Factorization of 713 is 23 x 31

Prime Factorization of 26 is 2 x 13

Prime Factorization of 420 is 2 x 2 x 3 x 5 x 7

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(551, 713) = 392863

GCD(551, 713) = ( 551 x 713 ) / 392863

GCD(551, 713) = 392863 / 392863

GCD(551, 713) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 26

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

LCM(1, 26) = 26

GCD(1, 26) = ( 1 x 26 ) / 26

GCD(1, 26) = 26 / 26

GCD(1, 26) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 420

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

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

GCD(1, 420) = 420 / 420

GCD(1, 420) = 1

GCD of 551, 713, 26, 420 is 1
