GCD of 800, 450, 645, 979 is 1
GCD(800, 450, 645, 979) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 800, 450, 645, 979 is 1
GCD(800, 450, 645, 979) = 1
Given Input numbers are 800, 450, 645, 979
To find the GCD of numbers using factoring list out all the divisors of each number

1, 11, 89, 979
Greatest Common Divisior
We found the divisors of 800, 450, 645, 979 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 800, 450, 645, 979 is 1.
Therefore, GCD of numbers 800, 450, 645, 979 is 1
Given Input Data is 800, 450, 645, 979
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 800 is 2 x 2 x 2 x 2 x 2 x 5 x 5
Prime Factorization of 450 is 2 x 3 x 3 x 5 x 5
Prime Factorization of 645 is 3 x 5 x 43
Prime Factorization of 979 is 11 x 89
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(800, 450) = 7200
GCD(800, 450) = ( 800 x 450 ) / 7200
GCD(800, 450) = 360000 / 7200
GCD(800, 450) = 50
Step2:
Here we consider the GCD from the above i.e. 50 as first number and the next as 645
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(50, 645) = 6450
GCD(50, 645) = ( 50 x 645 ) / 6450
GCD(50, 645) = 32250 / 6450
GCD(50, 645) = 5
Step3:
Here we consider the GCD from the above i.e. 5 as first number and the next as 979
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 979) = 4895
GCD(5, 979) = ( 5 x 979 ) / 4895
GCD(5, 979) = 4895 / 4895
GCD(5, 979) = 1
GCD of 800, 450, 645, 979 is 1
