Greatest Common Divisior

We found the divisors of 85, 5, 60, 87 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 85, 5, 60, 87 is 1.

Therefore, GCD of numbers 85, 5, 60, 87 is 1

Given Input Data is 85, 5, 60, 87

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

Prime Factorization of 85 is 5 x 17

Prime Factorization of 5 is 5

Prime Factorization of 60 is 2 x 2 x 3 x 5

Prime Factorization of 87 is 3 x 29

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(85, 5) = 85

GCD(85, 5) = ( 85 x 5 ) / 85

GCD(85, 5) = 425 / 85

GCD(85, 5) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 60

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

LCM(5, 60) = 60

GCD(5, 60) = ( 5 x 60 ) / 60

GCD(5, 60) = 300 / 60

GCD(5, 60) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 87

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

LCM(5, 87) = 435

GCD(5, 87) = ( 5 x 87 ) / 435

GCD(5, 87) = 435 / 435

GCD(5, 87) = 1

GCD of 85, 5, 60, 87 is 1
