Given Input Data is 290, 840, 253

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

Prime Factorization of 290 is 2 x 5 x 29

Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7

Prime Factorization of 253 is 11 x 23

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(290, 840) = 24360

GCD(290, 840) = ( 290 x 840 ) / 24360

GCD(290, 840) = 243600 / 24360

GCD(290, 840) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 253

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

LCM(10, 253) = 2530

GCD(10, 253) = ( 10 x 253 ) / 2530

GCD(10, 253) = 2530 / 2530

GCD(10, 253) = 1

GCD of 290, 840, 253 is 1
