Therefore, GCD of numbers 70, 885, 145, 864 is 1

Given Input Data is 70, 885, 145, 864

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

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 885 is 3 x 5 x 59

Prime Factorization of 145 is 5 x 29

Prime Factorization of 864 is 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

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(70, 885) = 12390

GCD(70, 885) = ( 70 x 885 ) / 12390

GCD(70, 885) = 61950 / 12390

GCD(70, 885) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 145

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

LCM(5, 145) = 145

GCD(5, 145) = ( 5 x 145 ) / 145

GCD(5, 145) = 725 / 145

GCD(5, 145) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 864

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

LCM(5, 864) = 4320

GCD(5, 864) = ( 5 x 864 ) / 4320

GCD(5, 864) = 4320 / 4320

GCD(5, 864) = 1

GCD of 70, 885, 145, 864 is 1
