Make use of GCD Calculator to determine the Greatest Common Divisor of 447, 220, 67, 817 i.e. 1 largest integer that divides all the numbers equally.
GCD of 447, 220, 67, 817 is 1
GCD(447, 220, 67, 817) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 447, 220, 67, 817 is 1
GCD(447, 220, 67, 817) = 1
Given Input numbers are 447, 220, 67, 817
To find the GCD of numbers using factoring list out all the divisors of each number

1, 67
Divisors of 817
List of positive integer divisors of 817 that divides 817 without a remainder.
1, 19, 43, 817
Greatest Common Divisior
We found the divisors of 447, 220, 67, 817 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 447, 220, 67, 817 is 1.
Therefore, GCD of numbers 447, 220, 67, 817 is 1
Given Input Data is 447, 220, 67, 817
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 447 is 3 x 149
Prime Factorization of 220 is 2 x 2 x 5 x 11
Prime Factorization of 67 is 67
Prime Factorization of 817 is 19 x 43
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(447, 220) = 98340
GCD(447, 220) = ( 447 x 220 ) / 98340
GCD(447, 220) = 98340 / 98340
GCD(447, 220) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 67
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 67) = 67
GCD(1, 67) = ( 1 x 67 ) / 67
GCD(1, 67) = 67 / 67
GCD(1, 67) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 817
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 817) = 817
GCD(1, 817) = ( 1 x 817 ) / 817
GCD(1, 817) = 817 / 817
GCD(1, 817) = 1
GCD of 447, 220, 67, 817 is 1
