Make use of GCD Calculator to determine the Greatest Common Divisor of 455, 458, 221, 916 i.e. 1 largest integer that divides all the numbers equally.
GCD of 455, 458, 221, 916 is 1
GCD(455, 458, 221, 916) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 455, 458, 221, 916 is 1
GCD(455, 458, 221, 916) = 1
Given Input numbers are 455, 458, 221, 916
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 4, 229, 458, 916
Greatest Common Divisior
We found the divisors of 455, 458, 221, 916 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 455, 458, 221, 916 is 1.
Therefore, GCD of numbers 455, 458, 221, 916 is 1
Given Input Data is 455, 458, 221, 916
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 455 is 5 x 7 x 13
Prime Factorization of 458 is 2 x 229
Prime Factorization of 221 is 13 x 17
Prime Factorization of 916 is 2 x 2 x 229
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(455, 458) = 208390
GCD(455, 458) = ( 455 x 458 ) / 208390
GCD(455, 458) = 208390 / 208390
GCD(455, 458) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 221
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
GCD(1, 221) = 221 / 221
GCD(1, 221) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 916
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 916) = 916
GCD(1, 916) = ( 1 x 916 ) / 916
GCD(1, 916) = 916 / 916
GCD(1, 916) = 1
GCD of 455, 458, 221, 916 is 1
