Make use of GCD Calculator to determine the Greatest Common Divisor of 416, 171, 21, 173 i.e. 1 largest integer that divides all the numbers equally.
GCD of 416, 171, 21, 173 is 1
GCD(416, 171, 21, 173) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 416, 171, 21, 173 is 1
GCD(416, 171, 21, 173) = 1
Given Input numbers are 416, 171, 21, 173
To find the GCD of numbers using factoring list out all the divisors of each number

Divisors of 173
List of positive integer divisors of 173 that divides 173 without a remainder.
1, 173
Greatest Common Divisior
We found the divisors of 416, 171, 21, 173 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 416, 171, 21, 173 is 1.
Therefore, GCD of numbers 416, 171, 21, 173 is 1
Given Input Data is 416, 171, 21, 173
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 416 is 2 x 2 x 2 x 2 x 2 x 13
Prime Factorization of 171 is 3 x 3 x 19
Prime Factorization of 21 is 3 x 7
Prime Factorization of 173 is 173
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(416, 171) = 71136
GCD(416, 171) = ( 416 x 171 ) / 71136
GCD(416, 171) = 71136 / 71136
GCD(416, 171) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 21
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 21) = 21
GCD(1, 21) = ( 1 x 21 ) / 21
GCD(1, 21) = 21 / 21
GCD(1, 21) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 173
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 173) = 173
GCD(1, 173) = ( 1 x 173 ) / 173
GCD(1, 173) = 173 / 173
GCD(1, 173) = 1
GCD of 416, 171, 21, 173 is 1
