Therefore, GCD of numbers 245, 870, 347, 606 is 1

Given Input Data is 245, 870, 347, 606

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

Prime Factorization of 245 is 5 x 7 x 7

Prime Factorization of 870 is 2 x 3 x 5 x 29

Prime Factorization of 347 is 347

Prime Factorization of 606 is 2 x 3 x 101

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(245, 870) = 42630

GCD(245, 870) = ( 245 x 870 ) / 42630

GCD(245, 870) = 213150 / 42630

GCD(245, 870) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 347

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

LCM(5, 347) = 1735

GCD(5, 347) = ( 5 x 347 ) / 1735

GCD(5, 347) = 1735 / 1735

GCD(5, 347) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 606

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

LCM(1, 606) = 606

GCD(1, 606) = ( 1 x 606 ) / 606

GCD(1, 606) = 606 / 606

GCD(1, 606) = 1

GCD of 245, 870, 347, 606 is 1
