Greatest Common Divisior

We found the divisors of 777, 781, 72, 281 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 777, 781, 72, 281 is 1.

Therefore, GCD of numbers 777, 781, 72, 281 is 1

Given Input Data is 777, 781, 72, 281

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

Prime Factorization of 777 is 3 x 7 x 37

Prime Factorization of 781 is 11 x 71

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

Prime Factorization of 281 is 281

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(777, 781) = 606837

GCD(777, 781) = ( 777 x 781 ) / 606837

GCD(777, 781) = 606837 / 606837

GCD(777, 781) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 72

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

LCM(1, 72) = 72

GCD(1, 72) = ( 1 x 72 ) / 72

GCD(1, 72) = 72 / 72

GCD(1, 72) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 281

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

LCM(1, 281) = 281

GCD(1, 281) = ( 1 x 281 ) / 281

GCD(1, 281) = 281 / 281

GCD(1, 281) = 1

GCD of 777, 781, 72, 281 is 1
