Greatest Common Divisior

We found the divisors of 48, 8, 72, 85 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 48, 8, 72, 85 is 1.

Therefore, GCD of numbers 48, 8, 72, 85 is 1

Given Input Data is 48, 8, 72, 85

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

Prime Factorization of 48 is 2 x 2 x 2 x 2 x 3

Prime Factorization of 8 is 2 x 2 x 2

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

Prime Factorization of 85 is 5 x 17

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(48, 8) = 48

GCD(48, 8) = ( 48 x 8 ) / 48

GCD(48, 8) = 384 / 48

GCD(48, 8) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 72

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

LCM(8, 72) = 72

GCD(8, 72) = ( 8 x 72 ) / 72

GCD(8, 72) = 576 / 72

GCD(8, 72) = 8

Step3:

Here we consider the GCD from the above i.e. 8 as first number and the next as 85

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

LCM(8, 85) = 680

GCD(8, 85) = ( 8 x 85 ) / 680

GCD(8, 85) = 680 / 680

GCD(8, 85) = 1

GCD of 48, 8, 72, 85 is 1
