Therefore, GCD of numbers 876, 240, 20, 837 is 1

Given Input Data is 876, 240, 20, 837

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

Prime Factorization of 876 is 2 x 2 x 3 x 73

Prime Factorization of 240 is 2 x 2 x 2 x 2 x 3 x 5

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 837 is 3 x 3 x 3 x 31

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(876, 240) = 17520

GCD(876, 240) = ( 876 x 240 ) / 17520

GCD(876, 240) = 210240 / 17520

GCD(876, 240) = 12

Step2:

Here we consider the GCD from the above i.e. 12 as first number and the next as 20

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

LCM(12, 20) = 60

GCD(12, 20) = ( 12 x 20 ) / 60

GCD(12, 20) = 240 / 60

GCD(12, 20) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 837

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

LCM(4, 837) = 3348

GCD(4, 837) = ( 4 x 837 ) / 3348

GCD(4, 837) = 3348 / 3348

GCD(4, 837) = 1

GCD of 876, 240, 20, 837 is 1
