Therefore, GCD of numbers 707, 783, 409 is 1

Given Input Data is 707, 783, 409

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

Prime Factorization of 707 is 7 x 101

Prime Factorization of 783 is 3 x 3 x 3 x 29

Prime Factorization of 409 is 409

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(707, 783) = 553581

GCD(707, 783) = ( 707 x 783 ) / 553581

GCD(707, 783) = 553581 / 553581

GCD(707, 783) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 409

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

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

GCD(1, 409) = 409 / 409

GCD(1, 409) = 1

GCD of 707, 783, 409 is 1
