Given Input Data is 265, 945, 846, 639

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

Prime Factorization of 265 is 5 x 53

Prime Factorization of 945 is 3 x 3 x 3 x 5 x 7

Prime Factorization of 846 is 2 x 3 x 3 x 47

Prime Factorization of 639 is 3 x 3 x 71

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(265, 945) = 50085

GCD(265, 945) = ( 265 x 945 ) / 50085

GCD(265, 945) = 250425 / 50085

GCD(265, 945) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 846

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

LCM(5, 846) = 4230

GCD(5, 846) = ( 5 x 846 ) / 4230

GCD(5, 846) = 4230 / 4230

GCD(5, 846) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 639

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

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

GCD(1, 639) = 639 / 639

GCD(1, 639) = 1

GCD of 265, 945, 846, 639 is 1
