Therefore, GCD of numbers 840, 775, 883, 391 is 1

Given Input Data is 840, 775, 883, 391

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 775 is 5 x 5 x 31

Prime Factorization of 883 is 883

Prime Factorization of 391 is 17 x 23

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, 775) = 130200

GCD(840, 775) = ( 840 x 775 ) / 130200

GCD(840, 775) = 651000 / 130200

GCD(840, 775) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 883

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

LCM(5, 883) = 4415

GCD(5, 883) = ( 5 x 883 ) / 4415

GCD(5, 883) = 4415 / 4415

GCD(5, 883) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 391

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

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

GCD(1, 391) = 391 / 391

GCD(1, 391) = 1

GCD of 840, 775, 883, 391 is 1
