Therefore, GCD of numbers 28, 273, 975, 479 is 1

Given Input Data is 28, 273, 975, 479

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

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 273 is 3 x 7 x 13

Prime Factorization of 975 is 3 x 5 x 5 x 13

Prime Factorization of 479 is 479

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(28, 273) = 1092

GCD(28, 273) = ( 28 x 273 ) / 1092

GCD(28, 273) = 7644 / 1092

GCD(28, 273) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 975

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

LCM(7, 975) = 6825

GCD(7, 975) = ( 7 x 975 ) / 6825

GCD(7, 975) = 6825 / 6825

GCD(7, 975) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 479

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

LCM(1, 479) = 479

GCD(1, 479) = ( 1 x 479 ) / 479

GCD(1, 479) = 479 / 479

GCD(1, 479) = 1

GCD of 28, 273, 975, 479 is 1
