Therefore, GCD of numbers 781, 730, 45, 863 is 1

Given Input Data is 781, 730, 45, 863

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

Prime Factorization of 781 is 11 x 71

Prime Factorization of 730 is 2 x 5 x 73

Prime Factorization of 45 is 3 x 3 x 5

Prime Factorization of 863 is 863

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(781, 730) = 570130

GCD(781, 730) = ( 781 x 730 ) / 570130

GCD(781, 730) = 570130 / 570130

GCD(781, 730) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 45

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

LCM(1, 45) = 45

GCD(1, 45) = ( 1 x 45 ) / 45

GCD(1, 45) = 45 / 45

GCD(1, 45) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 863

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

LCM(1, 863) = 863

GCD(1, 863) = ( 1 x 863 ) / 863

GCD(1, 863) = 863 / 863

GCD(1, 863) = 1

GCD of 781, 730, 45, 863 is 1
