Given Input Data is 770, 225, 63, 286

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

Prime Factorization of 770 is 2 x 5 x 7 x 11

Prime Factorization of 225 is 3 x 3 x 5 x 5

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 286 is 2 x 11 x 13

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(770, 225) = 34650

GCD(770, 225) = ( 770 x 225 ) / 34650

GCD(770, 225) = 173250 / 34650

GCD(770, 225) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 63

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

LCM(5, 63) = 315

GCD(5, 63) = ( 5 x 63 ) / 315

GCD(5, 63) = 315 / 315

GCD(5, 63) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 286

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

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

GCD(1, 286) = 286 / 286

GCD(1, 286) = 1

GCD of 770, 225, 63, 286 is 1
