Greatest Common Divisior

We found the divisors of 35, 42, 65 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 35, 42, 65 is 1.

Therefore, GCD of numbers 35, 42, 65 is 1

Given Input Data is 35, 42, 65

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

Prime Factorization of 35 is 5 x 7

Prime Factorization of 42 is 2 x 3 x 7

Prime Factorization of 65 is 5 x 13

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(35, 42) = 210

GCD(35, 42) = ( 35 x 42 ) / 210

GCD(35, 42) = 1470 / 210

GCD(35, 42) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 65

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

LCM(7, 65) = 455

GCD(7, 65) = ( 7 x 65 ) / 455

GCD(7, 65) = 455 / 455

GCD(7, 65) = 1

GCD of 35, 42, 65 is 1
