Therefore, GCD of numbers 253, 690, 254 is 1

Given Input Data is 253, 690, 254

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

Prime Factorization of 253 is 11 x 23

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

Prime Factorization of 254 is 2 x 127

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(253, 690) = 7590

GCD(253, 690) = ( 253 x 690 ) / 7590

GCD(253, 690) = 174570 / 7590

GCD(253, 690) = 23

Step2:

Here we consider the GCD from the above i.e. 23 as first number and the next as 254

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

LCM(23, 254) = 5842

GCD(23, 254) = ( 23 x 254 ) / 5842

GCD(23, 254) = 5842 / 5842

GCD(23, 254) = 1

GCD of 253, 690, 254 is 1
