Therefore, GCD of numbers 662, 818, 425 is 1

Given Input Data is 662, 818, 425

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

Prime Factorization of 662 is 2 x 331

Prime Factorization of 818 is 2 x 409

Prime Factorization of 425 is 5 x 5 x 17

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(662, 818) = 270758

GCD(662, 818) = ( 662 x 818 ) / 270758

GCD(662, 818) = 541516 / 270758

GCD(662, 818) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 425

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

LCM(2, 425) = 850

GCD(2, 425) = ( 2 x 425 ) / 850

GCD(2, 425) = 850 / 850

GCD(2, 425) = 1

GCD of 662, 818, 425 is 1
