Greatest Common Divisior

We found the divisors of 77, 10, 11, 25 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 77, 10, 11, 25 is 1.

Therefore, GCD of numbers 77, 10, 11, 25 is 1

Given Input Data is 77, 10, 11, 25

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

Prime Factorization of 77 is 7 x 11

Prime Factorization of 10 is 2 x 5

Prime Factorization of 11 is 11

Prime Factorization of 25 is 5 x 5

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(77, 10) = 770

GCD(77, 10) = ( 77 x 10 ) / 770

GCD(77, 10) = 770 / 770

GCD(77, 10) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 11

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

LCM(1, 11) = 11

GCD(1, 11) = ( 1 x 11 ) / 11

GCD(1, 11) = 11 / 11

GCD(1, 11) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 25

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

LCM(1, 25) = 25

GCD(1, 25) = ( 1 x 25 ) / 25

GCD(1, 25) = 25 / 25

GCD(1, 25) = 1

GCD of 77, 10, 11, 25 is 1
