Therefore, GCD of numbers 840, 836, 847, 388 is 1

Given Input Data is 840, 836, 847, 388

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

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

Prime Factorization of 836 is 2 x 2 x 11 x 19

Prime Factorization of 847 is 7 x 11 x 11

Prime Factorization of 388 is 2 x 2 x 97

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(840, 836) = 175560

GCD(840, 836) = ( 840 x 836 ) / 175560

GCD(840, 836) = 702240 / 175560

GCD(840, 836) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 847

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

LCM(4, 847) = 3388

GCD(4, 847) = ( 4 x 847 ) / 3388

GCD(4, 847) = 3388 / 3388

GCD(4, 847) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 388

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

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

GCD(1, 388) = 388 / 388

GCD(1, 388) = 1

GCD of 840, 836, 847, 388 is 1
