Therefore, GCD of numbers 273, 390, 691, 763 is 1

Given Input Data is 273, 390, 691, 763

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

Prime Factorization of 273 is 3 x 7 x 13

Prime Factorization of 390 is 2 x 3 x 5 x 13

Prime Factorization of 691 is 691

Prime Factorization of 763 is 7 x 109

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(273, 390) = 2730

GCD(273, 390) = ( 273 x 390 ) / 2730

GCD(273, 390) = 106470 / 2730

GCD(273, 390) = 39

Step2:

Here we consider the GCD from the above i.e. 39 as first number and the next as 691

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

LCM(39, 691) = 26949

GCD(39, 691) = ( 39 x 691 ) / 26949

GCD(39, 691) = 26949 / 26949

GCD(39, 691) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 763

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

LCM(1, 763) = 763

GCD(1, 763) = ( 1 x 763 ) / 763

GCD(1, 763) = 763 / 763

GCD(1, 763) = 1

GCD of 273, 390, 691, 763 is 1
