Therefore, GCD of numbers 879, 840, 87, 284 is 1

Given Input Data is 879, 840, 87, 284

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

Prime Factorization of 879 is 3 x 293

Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7

Prime Factorization of 87 is 3 x 29

Prime Factorization of 284 is 2 x 2 x 71

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(879, 840) = 246120

GCD(879, 840) = ( 879 x 840 ) / 246120

GCD(879, 840) = 738360 / 246120

GCD(879, 840) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 87

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

LCM(3, 87) = 87

GCD(3, 87) = ( 3 x 87 ) / 87

GCD(3, 87) = 261 / 87

GCD(3, 87) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 284

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

LCM(3, 284) = 852

GCD(3, 284) = ( 3 x 284 ) / 852

GCD(3, 284) = 852 / 852

GCD(3, 284) = 1

GCD of 879, 840, 87, 284 is 1
