Therefore, GCD of numbers 135, 247, 803 is 1

Given Input Data is 135, 247, 803

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

Prime Factorization of 135 is 3 x 3 x 3 x 5

Prime Factorization of 247 is 13 x 19

Prime Factorization of 803 is 11 x 73

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(135, 247) = 33345

GCD(135, 247) = ( 135 x 247 ) / 33345

GCD(135, 247) = 33345 / 33345

GCD(135, 247) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 803

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

LCM(1, 803) = 803

GCD(1, 803) = ( 1 x 803 ) / 803

GCD(1, 803) = 803 / 803

GCD(1, 803) = 1

GCD of 135, 247, 803 is 1
