Given Input Data is 868, 581, 43, 715

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

Prime Factorization of 868 is 2 x 2 x 7 x 31

Prime Factorization of 581 is 7 x 83

Prime Factorization of 43 is 43

Prime Factorization of 715 is 5 x 11 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(868, 581) = 72044

GCD(868, 581) = ( 868 x 581 ) / 72044

GCD(868, 581) = 504308 / 72044

GCD(868, 581) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 43

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

LCM(7, 43) = 301

GCD(7, 43) = ( 7 x 43 ) / 301

GCD(7, 43) = 301 / 301

GCD(7, 43) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 715

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

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

GCD(1, 715) = 715 / 715

GCD(1, 715) = 1

GCD of 868, 581, 43, 715 is 1
