Therefore, GCD of numbers 490, 685, 662 is 1

Given Input Data is 490, 685, 662

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

Prime Factorization of 490 is 2 x 5 x 7 x 7

Prime Factorization of 685 is 5 x 137

Prime Factorization of 662 is 2 x 331

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(490, 685) = 67130

GCD(490, 685) = ( 490 x 685 ) / 67130

GCD(490, 685) = 335650 / 67130

GCD(490, 685) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 662

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

LCM(5, 662) = 3310

GCD(5, 662) = ( 5 x 662 ) / 3310

GCD(5, 662) = 3310 / 3310

GCD(5, 662) = 1

GCD of 490, 685, 662 is 1
