Given Input Data is 280, 835, 48, 643

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

Prime Factorization of 280 is 2 x 2 x 2 x 5 x 7

Prime Factorization of 835 is 5 x 167

Prime Factorization of 48 is 2 x 2 x 2 x 2 x 3

Prime Factorization of 643 is 643

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(280, 835) = 46760

GCD(280, 835) = ( 280 x 835 ) / 46760

GCD(280, 835) = 233800 / 46760

GCD(280, 835) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 48

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

LCM(5, 48) = 240

GCD(5, 48) = ( 5 x 48 ) / 240

GCD(5, 48) = 240 / 240

GCD(5, 48) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 643

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

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

GCD(1, 643) = 643 / 643

GCD(1, 643) = 1

GCD of 280, 835, 48, 643 is 1
