Therefore, GCD of numbers 511, 249, 15, 653 is 1

Given Input Data is 511, 249, 15, 653

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

Prime Factorization of 511 is 7 x 73

Prime Factorization of 249 is 3 x 83

Prime Factorization of 15 is 3 x 5

Prime Factorization of 653 is 653

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(511, 249) = 127239

GCD(511, 249) = ( 511 x 249 ) / 127239

GCD(511, 249) = 127239 / 127239

GCD(511, 249) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 15

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

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

GCD(1, 15) = 15 / 15

GCD(1, 15) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 653

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

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

GCD(1, 653) = 653 / 653

GCD(1, 653) = 1

GCD of 511, 249, 15, 653 is 1
