Therefore, GCD of numbers 51, 231, 358, 215 is 1

Given Input Data is 51, 231, 358, 215

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

Prime Factorization of 51 is 3 x 17

Prime Factorization of 231 is 3 x 7 x 11

Prime Factorization of 358 is 2 x 179

Prime Factorization of 215 is 5 x 43

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(51, 231) = 3927

GCD(51, 231) = ( 51 x 231 ) / 3927

GCD(51, 231) = 11781 / 3927

GCD(51, 231) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 358

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

LCM(3, 358) = 1074

GCD(3, 358) = ( 3 x 358 ) / 1074

GCD(3, 358) = 1074 / 1074

GCD(3, 358) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 215

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

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

GCD(1, 215) = 215 / 215

GCD(1, 215) = 1

GCD of 51, 231, 358, 215 is 1
