Therefore, GCD of numbers 145, 285, 70, 901 is 1

Given Input Data is 145, 285, 70, 901

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

Prime Factorization of 145 is 5 x 29

Prime Factorization of 285 is 3 x 5 x 19

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 901 is 17 x 53

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(145, 285) = 8265

GCD(145, 285) = ( 145 x 285 ) / 8265

GCD(145, 285) = 41325 / 8265

GCD(145, 285) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 70

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

LCM(5, 70) = 70

GCD(5, 70) = ( 5 x 70 ) / 70

GCD(5, 70) = 350 / 70

GCD(5, 70) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 901

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

LCM(5, 901) = 4505

GCD(5, 901) = ( 5 x 901 ) / 4505

GCD(5, 901) = 4505 / 4505

GCD(5, 901) = 1

GCD of 145, 285, 70, 901 is 1
