Therefore, GCD of numbers 690, 190, 679, 730 is 1

Given Input Data is 690, 190, 679, 730

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

Prime Factorization of 690 is 2 x 3 x 5 x 23

Prime Factorization of 190 is 2 x 5 x 19

Prime Factorization of 679 is 7 x 97

Prime Factorization of 730 is 2 x 5 x 73

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(690, 190) = 13110

GCD(690, 190) = ( 690 x 190 ) / 13110

GCD(690, 190) = 131100 / 13110

GCD(690, 190) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 679

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

LCM(10, 679) = 6790

GCD(10, 679) = ( 10 x 679 ) / 6790

GCD(10, 679) = 6790 / 6790

GCD(10, 679) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 730

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

LCM(1, 730) = 730

GCD(1, 730) = ( 1 x 730 ) / 730

GCD(1, 730) = 730 / 730

GCD(1, 730) = 1

GCD of 690, 190, 679, 730 is 1
