Therefore, GCD of numbers 749, 820, 626 is 1

Given Input Data is 749, 820, 626

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

Prime Factorization of 749 is 7 x 107

Prime Factorization of 820 is 2 x 2 x 5 x 41

Prime Factorization of 626 is 2 x 313

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(749, 820) = 614180

GCD(749, 820) = ( 749 x 820 ) / 614180

GCD(749, 820) = 614180 / 614180

GCD(749, 820) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 626

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

LCM(1, 626) = 626

GCD(1, 626) = ( 1 x 626 ) / 626

GCD(1, 626) = 626 / 626

GCD(1, 626) = 1

GCD of 749, 820, 626 is 1
