Therefore, GCD of numbers 860, 370, 81, 406 is 1

Given Input Data is 860, 370, 81, 406

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

Prime Factorization of 860 is 2 x 2 x 5 x 43

Prime Factorization of 370 is 2 x 5 x 37

Prime Factorization of 81 is 3 x 3 x 3 x 3

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(860, 370) = 31820

GCD(860, 370) = ( 860 x 370 ) / 31820

GCD(860, 370) = 318200 / 31820

GCD(860, 370) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 81

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

LCM(10, 81) = 810

GCD(10, 81) = ( 10 x 81 ) / 810

GCD(10, 81) = 810 / 810

GCD(10, 81) = 1

Step3:

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 860, 370, 81, 406 is 1
