Given Input Data is 483, 245, 78, 208

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

Prime Factorization of 483 is 3 x 7 x 23

Prime Factorization of 245 is 5 x 7 x 7

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 208 is 2 x 2 x 2 x 2 x 13

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(483, 245) = 16905

GCD(483, 245) = ( 483 x 245 ) / 16905

GCD(483, 245) = 118335 / 16905

GCD(483, 245) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 78

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

LCM(7, 78) = 546

GCD(7, 78) = ( 7 x 78 ) / 546

GCD(7, 78) = 546 / 546

GCD(7, 78) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 208

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

LCM(1, 208) = 208

GCD(1, 208) = ( 1 x 208 ) / 208

GCD(1, 208) = 208 / 208

GCD(1, 208) = 1

GCD of 483, 245, 78, 208 is 1
