Therefore, GCD of numbers 840, 258, 415, 375 is 1

Given Input Data is 840, 258, 415, 375

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 258 is 2 x 3 x 43

Prime Factorization of 415 is 5 x 83

Prime Factorization of 375 is 3 x 5 x 5 x 5

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, 258) = 36120

GCD(840, 258) = ( 840 x 258 ) / 36120

GCD(840, 258) = 216720 / 36120

GCD(840, 258) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 415

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

LCM(6, 415) = 2490

GCD(6, 415) = ( 6 x 415 ) / 2490

GCD(6, 415) = 2490 / 2490

GCD(6, 415) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 375

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

LCM(1, 375) = 375

GCD(1, 375) = ( 1 x 375 ) / 375

GCD(1, 375) = 375 / 375

GCD(1, 375) = 1

GCD of 840, 258, 415, 375 is 1
