Therefore, GCD of numbers 715, 902, 68, 238 is 1

Given Input Data is 715, 902, 68, 238

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

Prime Factorization of 715 is 5 x 11 x 13

Prime Factorization of 902 is 2 x 11 x 41

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 238 is 2 x 7 x 17

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(715, 902) = 58630

GCD(715, 902) = ( 715 x 902 ) / 58630

GCD(715, 902) = 644930 / 58630

GCD(715, 902) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 68

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

LCM(11, 68) = 748

GCD(11, 68) = ( 11 x 68 ) / 748

GCD(11, 68) = 748 / 748

GCD(11, 68) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 238

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

LCM(1, 238) = 238

GCD(1, 238) = ( 1 x 238 ) / 238

GCD(1, 238) = 238 / 238

GCD(1, 238) = 1

GCD of 715, 902, 68, 238 is 1
