Therefore, GCD of numbers 149, 621, 406 is 1

Given Input Data is 149, 621, 406

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

Prime Factorization of 149 is 149

Prime Factorization of 621 is 3 x 3 x 3 x 23

Prime Factorization of 406 is 2 x 7 x 29

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(149, 621) = 92529

GCD(149, 621) = ( 149 x 621 ) / 92529

GCD(149, 621) = 92529 / 92529

GCD(149, 621) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 406

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

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

GCD(1, 406) = 406 / 406

GCD(1, 406) = 1

GCD of 149, 621, 406 is 1
