Given Input Data is 436, 636, 658, 945

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

Prime Factorization of 436 is 2 x 2 x 109

Prime Factorization of 636 is 2 x 2 x 3 x 53

Prime Factorization of 658 is 2 x 7 x 47

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

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(436, 636) = 69324

GCD(436, 636) = ( 436 x 636 ) / 69324

GCD(436, 636) = 277296 / 69324

GCD(436, 636) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 658

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

LCM(4, 658) = 1316

GCD(4, 658) = ( 4 x 658 ) / 1316

GCD(4, 658) = 2632 / 1316

GCD(4, 658) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 945

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

LCM(2, 945) = 1890

GCD(2, 945) = ( 2 x 945 ) / 1890

GCD(2, 945) = 1890 / 1890

GCD(2, 945) = 1

GCD of 436, 636, 658, 945 is 1
