Therefore, GCD of numbers 180, 980, 783, 904 is 1

Given Input Data is 180, 980, 783, 904

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

Prime Factorization of 180 is 2 x 2 x 3 x 3 x 5

Prime Factorization of 980 is 2 x 2 x 5 x 7 x 7

Prime Factorization of 783 is 3 x 3 x 3 x 29

Prime Factorization of 904 is 2 x 2 x 2 x 113

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(180, 980) = 8820

GCD(180, 980) = ( 180 x 980 ) / 8820

GCD(180, 980) = 176400 / 8820

GCD(180, 980) = 20

Step2:

Here we consider the GCD from the above i.e. 20 as first number and the next as 783

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

LCM(20, 783) = 15660

GCD(20, 783) = ( 20 x 783 ) / 15660

GCD(20, 783) = 15660 / 15660

GCD(20, 783) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 904

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

LCM(1, 904) = 904

GCD(1, 904) = ( 1 x 904 ) / 904

GCD(1, 904) = 904 / 904

GCD(1, 904) = 1

GCD of 180, 980, 783, 904 is 1
