Therefore, GCD of numbers 325, 351, 76, 820 is 1

Given Input Data is 325, 351, 76, 820

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

Prime Factorization of 325 is 5 x 5 x 13

Prime Factorization of 351 is 3 x 3 x 3 x 13

Prime Factorization of 76 is 2 x 2 x 19

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

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(325, 351) = 8775

GCD(325, 351) = ( 325 x 351 ) / 8775

GCD(325, 351) = 114075 / 8775

GCD(325, 351) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 76

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

LCM(13, 76) = 988

GCD(13, 76) = ( 13 x 76 ) / 988

GCD(13, 76) = 988 / 988

GCD(13, 76) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 820

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

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

GCD(1, 820) = 820 / 820

GCD(1, 820) = 1

GCD of 325, 351, 76, 820 is 1
