Greatest Common Divisior

We found the divisors of 98, 85, 87 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 98, 85, 87 is 1.

Therefore, GCD of numbers 98, 85, 87 is 1

Given Input Data is 98, 85, 87

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

Prime Factorization of 98 is 2 x 7 x 7

Prime Factorization of 85 is 5 x 17

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(98, 85) = 8330

GCD(98, 85) = ( 98 x 85 ) / 8330

GCD(98, 85) = 8330 / 8330

GCD(98, 85) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 87

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

LCM(1, 87) = 87

GCD(1, 87) = ( 1 x 87 ) / 87

GCD(1, 87) = 87 / 87

GCD(1, 87) = 1

GCD of 98, 85, 87 is 1
