Therefore, GCD of numbers 945, 711, 43, 293 is 1

Given Input Data is 945, 711, 43, 293

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

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

Prime Factorization of 711 is 3 x 3 x 79

Prime Factorization of 43 is 43

Prime Factorization of 293 is 293

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(945, 711) = 74655

GCD(945, 711) = ( 945 x 711 ) / 74655

GCD(945, 711) = 671895 / 74655

GCD(945, 711) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 43

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

LCM(9, 43) = 387

GCD(9, 43) = ( 9 x 43 ) / 387

GCD(9, 43) = 387 / 387

GCD(9, 43) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 293

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

LCM(1, 293) = 293

GCD(1, 293) = ( 1 x 293 ) / 293

GCD(1, 293) = 293 / 293

GCD(1, 293) = 1

GCD of 945, 711, 43, 293 is 1
