Therefore, GCD of numbers 90, 247, 244, 724 is 1

Given Input Data is 90, 247, 244, 724

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

Prime Factorization of 90 is 2 x 3 x 3 x 5

Prime Factorization of 247 is 13 x 19

Prime Factorization of 244 is 2 x 2 x 61

Prime Factorization of 724 is 2 x 2 x 181

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(90, 247) = 22230

GCD(90, 247) = ( 90 x 247 ) / 22230

GCD(90, 247) = 22230 / 22230

GCD(90, 247) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 244

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

LCM(1, 244) = 244

GCD(1, 244) = ( 1 x 244 ) / 244

GCD(1, 244) = 244 / 244

GCD(1, 244) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 724

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

LCM(1, 724) = 724

GCD(1, 724) = ( 1 x 724 ) / 724

GCD(1, 724) = 724 / 724

GCD(1, 724) = 1

GCD of 90, 247, 244, 724 is 1
