Therefore, GCD of numbers 802, 260, 393 is 1

Given Input Data is 802, 260, 393

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

Prime Factorization of 802 is 2 x 401

Prime Factorization of 260 is 2 x 2 x 5 x 13

Prime Factorization of 393 is 3 x 131

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(802, 260) = 104260

GCD(802, 260) = ( 802 x 260 ) / 104260

GCD(802, 260) = 208520 / 104260

GCD(802, 260) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 393

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

LCM(2, 393) = 786

GCD(2, 393) = ( 2 x 393 ) / 786

GCD(2, 393) = 786 / 786

GCD(2, 393) = 1

GCD of 802, 260, 393 is 1
