Given Input Data is 623, 840, 473, 282

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

Prime Factorization of 623 is 7 x 89

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

Prime Factorization of 473 is 11 x 43

Prime Factorization of 282 is 2 x 3 x 47

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(623, 840) = 74760

GCD(623, 840) = ( 623 x 840 ) / 74760

GCD(623, 840) = 523320 / 74760

GCD(623, 840) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 473

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

LCM(7, 473) = 3311

GCD(7, 473) = ( 7 x 473 ) / 3311

GCD(7, 473) = 3311 / 3311

GCD(7, 473) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 282

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

LCM(1, 282) = 282

GCD(1, 282) = ( 1 x 282 ) / 282

GCD(1, 282) = 282 / 282

GCD(1, 282) = 1

GCD of 623, 840, 473, 282 is 1
