Therefore, GCD of numbers 42, 621, 120, 950 is 1

Given Input Data is 42, 621, 120, 950

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

Prime Factorization of 42 is 2 x 3 x 7

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

Prime Factorization of 120 is 2 x 2 x 2 x 3 x 5

Prime Factorization of 950 is 2 x 5 x 5 x 19

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(42, 621) = 8694

GCD(42, 621) = ( 42 x 621 ) / 8694

GCD(42, 621) = 26082 / 8694

GCD(42, 621) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 120

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

LCM(3, 120) = 120

GCD(3, 120) = ( 3 x 120 ) / 120

GCD(3, 120) = 360 / 120

GCD(3, 120) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 950

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

LCM(3, 950) = 2850

GCD(3, 950) = ( 3 x 950 ) / 2850

GCD(3, 950) = 2850 / 2850

GCD(3, 950) = 1

GCD of 42, 621, 120, 950 is 1
