Therefore, GCD of numbers 603, 301, 320, 780 is 1

Given Input Data is 603, 301, 320, 780

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 301 is 7 x 43

Prime Factorization of 320 is 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime Factorization of 780 is 2 x 2 x 3 x 5 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, 301) = 181503

GCD(603, 301) = ( 603 x 301 ) / 181503

GCD(603, 301) = 181503 / 181503

GCD(603, 301) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 320

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

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

GCD(1, 320) = 320 / 320

GCD(1, 320) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 780

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

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

GCD(1, 780) = 780 / 780

GCD(1, 780) = 1

GCD of 603, 301, 320, 780 is 1
