Make use of GCD Calculator to determine the Greatest Common Divisor of 400, 221, 57, 917 i.e. 1 largest integer that divides all the numbers equally.
GCD of 400, 221, 57, 917 is 1
GCD(400, 221, 57, 917) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 400, 221, 57, 917 is 1
GCD(400, 221, 57, 917) = 1
Given Input numbers are 400, 221, 57, 917
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 400

1, 3, 19, 57
Divisors of 917
List of positive integer divisors of 917 that divides 917 without a remainder.
1, 7, 131, 917
Greatest Common Divisior
We found the divisors of 400, 221, 57, 917 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 400, 221, 57, 917 is 1.
Therefore, GCD of numbers 400, 221, 57, 917 is 1
Given Input Data is 400, 221, 57, 917
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 400 is 2 x 2 x 2 x 2 x 5 x 5
Prime Factorization of 221 is 13 x 17
Prime Factorization of 57 is 3 x 19
Prime Factorization of 917 is 7 x 131
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(400, 221) = 88400
GCD(400, 221) = ( 400 x 221 ) / 88400
GCD(400, 221) = 88400 / 88400
GCD(400, 221) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 57
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 57) = 57
GCD(1, 57) = ( 1 x 57 ) / 57
GCD(1, 57) = 57 / 57
GCD(1, 57) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 917
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 917) = 917
GCD(1, 917) = ( 1 x 917 ) / 917
GCD(1, 917) = 917 / 917
GCD(1, 917) = 1
GCD of 400, 221, 57, 917 is 1
