Greatest Common Divisior

We found the divisors of 86, 87, 67, 19 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 86, 87, 67, 19 is 1.

Therefore, GCD of numbers 86, 87, 67, 19 is 1

Given Input Data is 86, 87, 67, 19

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

Prime Factorization of 86 is 2 x 43

Prime Factorization of 87 is 3 x 29

Prime Factorization of 67 is 67

Prime Factorization of 19 is 19

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(86, 87) = 7482

GCD(86, 87) = ( 86 x 87 ) / 7482

GCD(86, 87) = 7482 / 7482

GCD(86, 87) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 67

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

LCM(1, 67) = 67

GCD(1, 67) = ( 1 x 67 ) / 67

GCD(1, 67) = 67 / 67

GCD(1, 67) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 19

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

LCM(1, 19) = 19

GCD(1, 19) = ( 1 x 19 ) / 19

GCD(1, 19) = 19 / 19

GCD(1, 19) = 1

GCD of 86, 87, 67, 19 is 1
