Therefore, GCD of numbers 840, 585, 88, 431 is 1

Given Input Data is 840, 585, 88, 431

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 585 is 3 x 3 x 5 x 13

Prime Factorization of 88 is 2 x 2 x 2 x 11

Prime Factorization of 431 is 431

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, 585) = 32760

GCD(840, 585) = ( 840 x 585 ) / 32760

GCD(840, 585) = 491400 / 32760

GCD(840, 585) = 15

Step2:

Here we consider the GCD from the above i.e. 15 as first number and the next as 88

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

LCM(15, 88) = 1320

GCD(15, 88) = ( 15 x 88 ) / 1320

GCD(15, 88) = 1320 / 1320

GCD(15, 88) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 431

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

LCM(1, 431) = 431

GCD(1, 431) = ( 1 x 431 ) / 431

GCD(1, 431) = 431 / 431

GCD(1, 431) = 1

GCD of 840, 585, 88, 431 is 1
