Make use of GCD Calculator to determine the Greatest Common Divisor of 981, 404, 521, 805 i.e. 1 largest integer that divides all the numbers equally.
GCD of 981, 404, 521, 805 is 1
GCD(981, 404, 521, 805) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 981, 404, 521, 805 is 1
GCD(981, 404, 521, 805) = 1
Given Input numbers are 981, 404, 521, 805
To find the GCD of numbers using factoring list out all the divisors of each number

1, 521
Divisors of 805
List of positive integer divisors of 805 that divides 805 without a remainder.
1, 5, 7, 23, 35, 115, 161, 805
Greatest Common Divisior
We found the divisors of 981, 404, 521, 805 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 981, 404, 521, 805 is 1.
Therefore, GCD of numbers 981, 404, 521, 805 is 1
Given Input Data is 981, 404, 521, 805
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 981 is 3 x 3 x 109
Prime Factorization of 404 is 2 x 2 x 101
Prime Factorization of 521 is 521
Prime Factorization of 805 is 5 x 7 x 23
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(981, 404) = 396324
GCD(981, 404) = ( 981 x 404 ) / 396324
GCD(981, 404) = 396324 / 396324
GCD(981, 404) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 521
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 521) = 521
GCD(1, 521) = ( 1 x 521 ) / 521
GCD(1, 521) = 521 / 521
GCD(1, 521) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 805
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
GCD(1, 805) = 805 / 805
GCD(1, 805) = 1
GCD of 981, 404, 521, 805 is 1
