Given Input Data is 225, 520, 490, 373

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

Prime Factorization of 225 is 3 x 3 x 5 x 5

Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13

Prime Factorization of 490 is 2 x 5 x 7 x 7

Prime Factorization of 373 is 373

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(225, 520) = 23400

GCD(225, 520) = ( 225 x 520 ) / 23400

GCD(225, 520) = 117000 / 23400

GCD(225, 520) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 490

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

LCM(5, 490) = 490

GCD(5, 490) = ( 5 x 490 ) / 490

GCD(5, 490) = 2450 / 490

GCD(5, 490) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 373

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

LCM(5, 373) = 1865

GCD(5, 373) = ( 5 x 373 ) / 1865

GCD(5, 373) = 1865 / 1865

GCD(5, 373) = 1

GCD of 225, 520, 490, 373 is 1
