Given Input Data is 775, 630, 699, 947

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

Prime Factorization of 775 is 5 x 5 x 31

Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7

Prime Factorization of 699 is 3 x 233

Prime Factorization of 947 is 947

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(775, 630) = 97650

GCD(775, 630) = ( 775 x 630 ) / 97650

GCD(775, 630) = 488250 / 97650

GCD(775, 630) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 699

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

LCM(5, 699) = 3495

GCD(5, 699) = ( 5 x 699 ) / 3495

GCD(5, 699) = 3495 / 3495

GCD(5, 699) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 947

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

LCM(1, 947) = 947

GCD(1, 947) = ( 1 x 947 ) / 947

GCD(1, 947) = 947 / 947

GCD(1, 947) = 1

GCD of 775, 630, 699, 947 is 1
