Therefore, GCD of numbers 940, 285, 42, 619 is 1

Given Input Data is 940, 285, 42, 619

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

Prime Factorization of 940 is 2 x 2 x 5 x 47

Prime Factorization of 285 is 3 x 5 x 19

Prime Factorization of 42 is 2 x 3 x 7

Prime Factorization of 619 is 619

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(940, 285) = 53580

GCD(940, 285) = ( 940 x 285 ) / 53580

GCD(940, 285) = 267900 / 53580

GCD(940, 285) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 42

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

LCM(5, 42) = 210

GCD(5, 42) = ( 5 x 42 ) / 210

GCD(5, 42) = 210 / 210

GCD(5, 42) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 619

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

LCM(1, 619) = 619

GCD(1, 619) = ( 1 x 619 ) / 619

GCD(1, 619) = 619 / 619

GCD(1, 619) = 1

GCD of 940, 285, 42, 619 is 1
