We found the divisors of 421, 775, 777, 716 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 421, 775, 777, 716 is 1.

Therefore, GCD of numbers 421, 775, 777, 716 is 1

Given Input Data is 421, 775, 777, 716

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

Prime Factorization of 421 is 421

Prime Factorization of 775 is 5 x 5 x 31

Prime Factorization of 777 is 3 x 7 x 37

Prime Factorization of 716 is 2 x 2 x 179

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(421, 775) = 326275

GCD(421, 775) = ( 421 x 775 ) / 326275

GCD(421, 775) = 326275 / 326275

GCD(421, 775) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 777

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

LCM(1, 777) = 777

GCD(1, 777) = ( 1 x 777 ) / 777

GCD(1, 777) = 777 / 777

GCD(1, 777) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 716

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

LCM(1, 716) = 716

GCD(1, 716) = ( 1 x 716 ) / 716

GCD(1, 716) = 716 / 716

GCD(1, 716) = 1

GCD of 421, 775, 777, 716 is 1
