Therefore, GCD of numbers 621, 696, 450, 430 is 1

Given Input Data is 621, 696, 450, 430

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

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

Prime Factorization of 696 is 2 x 2 x 2 x 3 x 29

Prime Factorization of 450 is 2 x 3 x 3 x 5 x 5

Prime Factorization of 430 is 2 x 5 x 43

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(621, 696) = 144072

GCD(621, 696) = ( 621 x 696 ) / 144072

GCD(621, 696) = 432216 / 144072

GCD(621, 696) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 450

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

LCM(3, 450) = 450

GCD(3, 450) = ( 3 x 450 ) / 450

GCD(3, 450) = 1350 / 450

GCD(3, 450) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 430

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

LCM(3, 430) = 1290

GCD(3, 430) = ( 3 x 430 ) / 1290

GCD(3, 430) = 1290 / 1290

GCD(3, 430) = 1

GCD of 621, 696, 450, 430 is 1
