Therefore, GCD of numbers 862, 978, 50, 515 is 1

Given Input Data is 862, 978, 50, 515

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

Prime Factorization of 862 is 2 x 431

Prime Factorization of 978 is 2 x 3 x 163

Prime Factorization of 50 is 2 x 5 x 5

Prime Factorization of 515 is 5 x 103

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(862, 978) = 421518

GCD(862, 978) = ( 862 x 978 ) / 421518

GCD(862, 978) = 843036 / 421518

GCD(862, 978) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 50

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

LCM(2, 50) = 50

GCD(2, 50) = ( 2 x 50 ) / 50

GCD(2, 50) = 100 / 50

GCD(2, 50) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 515

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

LCM(2, 515) = 1030

GCD(2, 515) = ( 2 x 515 ) / 1030

GCD(2, 515) = 1030 / 1030

GCD(2, 515) = 1

GCD of 862, 978, 50, 515 is 1
