Therefore, GCD of numbers 14, 392, 619, 781 is 1

Given Input Data is 14, 392, 619, 781

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

Prime Factorization of 14 is 2 x 7

Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7

Prime Factorization of 619 is 619

Prime Factorization of 781 is 11 x 71

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(14, 392) = 392

GCD(14, 392) = ( 14 x 392 ) / 392

GCD(14, 392) = 5488 / 392

GCD(14, 392) = 14

Step2:

Here we consider the GCD from the above i.e. 14 as first number and the next as 619

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

LCM(14, 619) = 8666

GCD(14, 619) = ( 14 x 619 ) / 8666

GCD(14, 619) = 8666 / 8666

GCD(14, 619) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 781

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

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

GCD(1, 781) = 781 / 781

GCD(1, 781) = 1

GCD of 14, 392, 619, 781 is 1
