Therefore, GCD of numbers 712, 940, 91, 291 is 1

Given Input Data is 712, 940, 91, 291

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

Prime Factorization of 712 is 2 x 2 x 2 x 89

Prime Factorization of 940 is 2 x 2 x 5 x 47

Prime Factorization of 91 is 7 x 13

Prime Factorization of 291 is 3 x 97

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(712, 940) = 167320

GCD(712, 940) = ( 712 x 940 ) / 167320

GCD(712, 940) = 669280 / 167320

GCD(712, 940) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 91

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

LCM(4, 91) = 364

GCD(4, 91) = ( 4 x 91 ) / 364

GCD(4, 91) = 364 / 364

GCD(4, 91) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 291

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

LCM(1, 291) = 291

GCD(1, 291) = ( 1 x 291 ) / 291

GCD(1, 291) = 291 / 291

GCD(1, 291) = 1

GCD of 712, 940, 91, 291 is 1
