Given Input Data is 740, 154, 820, 401

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

Prime Factorization of 740 is 2 x 2 x 5 x 37

Prime Factorization of 154 is 2 x 7 x 11

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

Prime Factorization of 401 is 401

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(740, 154) = 56980

GCD(740, 154) = ( 740 x 154 ) / 56980

GCD(740, 154) = 113960 / 56980

GCD(740, 154) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 820

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

LCM(2, 820) = 820

GCD(2, 820) = ( 2 x 820 ) / 820

GCD(2, 820) = 1640 / 820

GCD(2, 820) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 401

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

LCM(2, 401) = 802

GCD(2, 401) = ( 2 x 401 ) / 802

GCD(2, 401) = 802 / 802

GCD(2, 401) = 1

GCD of 740, 154, 820, 401 is 1
