Therefore, GCD of numbers 721, 578, 265 is 1

Given Input Data is 721, 578, 265

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

Prime Factorization of 721 is 7 x 103

Prime Factorization of 578 is 2 x 17 x 17

Prime Factorization of 265 is 5 x 53

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(721, 578) = 416738

GCD(721, 578) = ( 721 x 578 ) / 416738

GCD(721, 578) = 416738 / 416738

GCD(721, 578) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 265

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

LCM(1, 265) = 265

GCD(1, 265) = ( 1 x 265 ) / 265

GCD(1, 265) = 265 / 265

GCD(1, 265) = 1

GCD of 721, 578, 265 is 1
