Given Input Data is 603, 802, 25, 169

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

Prime Factorization of 603 is 3 x 3 x 67

Prime Factorization of 802 is 2 x 401

Prime Factorization of 25 is 5 x 5

Prime Factorization of 169 is 13 x 13

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(603, 802) = 483606

GCD(603, 802) = ( 603 x 802 ) / 483606

GCD(603, 802) = 483606 / 483606

GCD(603, 802) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 25

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

LCM(1, 25) = 25

GCD(1, 25) = ( 1 x 25 ) / 25

GCD(1, 25) = 25 / 25

GCD(1, 25) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 169

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

LCM(1, 169) = 169

GCD(1, 169) = ( 1 x 169 ) / 169

GCD(1, 169) = 169 / 169

GCD(1, 169) = 1

GCD of 603, 802, 25, 169 is 1
