Therefore, GCD of numbers 462, 214, 780, 555 is 1

Given Input Data is 462, 214, 780, 555

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

Prime Factorization of 462 is 2 x 3 x 7 x 11

Prime Factorization of 214 is 2 x 107

Prime Factorization of 780 is 2 x 2 x 3 x 5 x 13

Prime Factorization of 555 is 3 x 5 x 37

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(462, 214) = 49434

GCD(462, 214) = ( 462 x 214 ) / 49434

GCD(462, 214) = 98868 / 49434

GCD(462, 214) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 780

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

LCM(2, 780) = 780

GCD(2, 780) = ( 2 x 780 ) / 780

GCD(2, 780) = 1560 / 780

GCD(2, 780) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 555

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

LCM(2, 555) = 1110

GCD(2, 555) = ( 2 x 555 ) / 1110

GCD(2, 555) = 1110 / 1110

GCD(2, 555) = 1

GCD of 462, 214, 780, 555 is 1
