Therefore, GCD of numbers 268, 603, 65, 798 is 1

Given Input Data is 268, 603, 65, 798

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

Prime Factorization of 268 is 2 x 2 x 67

Prime Factorization of 603 is 3 x 3 x 67

Prime Factorization of 65 is 5 x 13

Prime Factorization of 798 is 2 x 3 x 7 x 19

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(268, 603) = 2412

GCD(268, 603) = ( 268 x 603 ) / 2412

GCD(268, 603) = 161604 / 2412

GCD(268, 603) = 67

Step2:

Here we consider the GCD from the above i.e. 67 as first number and the next as 65

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

LCM(67, 65) = 4355

GCD(67, 65) = ( 67 x 65 ) / 4355

GCD(67, 65) = 4355 / 4355

GCD(67, 65) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 798

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

LCM(1, 798) = 798

GCD(1, 798) = ( 1 x 798 ) / 798

GCD(1, 798) = 798 / 798

GCD(1, 798) = 1

GCD of 268, 603, 65, 798 is 1
