Therefore, GCD of numbers 72, 336, 242, 781 is 1

Given Input Data is 72, 336, 242, 781

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

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

Prime Factorization of 336 is 2 x 2 x 2 x 2 x 3 x 7

Prime Factorization of 242 is 2 x 11 x 11

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(72, 336) = 1008

GCD(72, 336) = ( 72 x 336 ) / 1008

GCD(72, 336) = 24192 / 1008

GCD(72, 336) = 24

Step2:

Here we consider the GCD from the above i.e. 24 as first number and the next as 242

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

LCM(24, 242) = 2904

GCD(24, 242) = ( 24 x 242 ) / 2904

GCD(24, 242) = 5808 / 2904

GCD(24, 242) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 781

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

LCM(2, 781) = 1562

GCD(2, 781) = ( 2 x 781 ) / 1562

GCD(2, 781) = 1562 / 1562

GCD(2, 781) = 1

GCD of 72, 336, 242, 781 is 1
