Greatest Common Divisior

We found the divisors of 65, 63, 35, 61 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 65, 63, 35, 61 is 1.

Therefore, GCD of numbers 65, 63, 35, 61 is 1

Given Input Data is 65, 63, 35, 61

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

Prime Factorization of 65 is 5 x 13

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 35 is 5 x 7

Prime Factorization of 61 is 61

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(65, 63) = 4095

GCD(65, 63) = ( 65 x 63 ) / 4095

GCD(65, 63) = 4095 / 4095

GCD(65, 63) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 35

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

LCM(1, 35) = 35

GCD(1, 35) = ( 1 x 35 ) / 35

GCD(1, 35) = 35 / 35

GCD(1, 35) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 61

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

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

GCD(1, 61) = 61 / 61

GCD(1, 61) = 1

GCD of 65, 63, 35, 61 is 1
