Therefore, GCD of numbers 651, 686, 71, 699 is 1

Given Input Data is 651, 686, 71, 699

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

Prime Factorization of 651 is 3 x 7 x 31

Prime Factorization of 686 is 2 x 7 x 7 x 7

Prime Factorization of 71 is 71

Prime Factorization of 699 is 3 x 233

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(651, 686) = 63798

GCD(651, 686) = ( 651 x 686 ) / 63798

GCD(651, 686) = 446586 / 63798

GCD(651, 686) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 71

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

LCM(7, 71) = 497

GCD(7, 71) = ( 7 x 71 ) / 497

GCD(7, 71) = 497 / 497

GCD(7, 71) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 699

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

LCM(1, 699) = 699

GCD(1, 699) = ( 1 x 699 ) / 699

GCD(1, 699) = 699 / 699

GCD(1, 699) = 1

GCD of 651, 686, 71, 699 is 1
