Make use of GCD Calculator to determine the Greatest Common Divisor of 401, 756, 71, 447 i.e. 1 largest integer that divides all the numbers equally.
GCD of 401, 756, 71, 447 is 1
GCD(401, 756, 71, 447) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 401, 756, 71, 447 is 1
GCD(401, 756, 71, 447) = 1
Given Input numbers are 401, 756, 71, 447
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 401

1, 3, 149, 447
Greatest Common Divisior
We found the divisors of 401, 756, 71, 447 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 401, 756, 71, 447 is 1.
Therefore, GCD of numbers 401, 756, 71, 447 is 1
Given Input Data is 401, 756, 71, 447
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 401 is 401
Prime Factorization of 756 is 2 x 2 x 3 x 3 x 3 x 7
Prime Factorization of 71 is 71
Prime Factorization of 447 is 3 x 149
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(401, 756) = 303156
GCD(401, 756) = ( 401 x 756 ) / 303156
GCD(401, 756) = 303156 / 303156
GCD(401, 756) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 71
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 71) = 71
GCD(1, 71) = ( 1 x 71 ) / 71
GCD(1, 71) = 71 / 71
GCD(1, 71) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 447
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 447) = 447
GCD(1, 447) = ( 1 x 447 ) / 447
GCD(1, 447) = 447 / 447
GCD(1, 447) = 1
GCD of 401, 756, 71, 447 is 1
