1, 2, 349, 698
Greatest Common Divisior
We found the divisors of 821, 844, 698 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 821, 844, 698 is 1.
Therefore, GCD of numbers 821, 844, 698 is 1
Given Input Data is 821, 844, 698
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 821 is 821
Prime Factorization of 844 is 2 x 2 x 211
Prime Factorization of 698 is 2 x 349
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(821, 844) = 692924
GCD(821, 844) = ( 821 x 844 ) / 692924
GCD(821, 844) = 692924 / 692924
GCD(821, 844) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 698
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 698) = 698
GCD(1, 698) = ( 1 x 698 ) / 698
GCD(1, 698) = 698 / 698
GCD(1, 698) = 1
GCD of 821, 844, 698 is 1
