Greatest Common Divisior
We found the divisors of 640, 505, 824, 894 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 640, 505, 824, 894 is 1.
Therefore, GCD of numbers 640, 505, 824, 894 is 1
Given Input Data is 640, 505, 824, 894
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5
Prime Factorization of 505 is 5 x 101
Prime Factorization of 824 is 2 x 2 x 2 x 103
Prime Factorization of 894 is 2 x 3 x 149
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(640, 505) = 64640
GCD(640, 505) = ( 640 x 505 ) / 64640
GCD(640, 505) = 323200 / 64640
GCD(640, 505) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 824
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 824) = 4120
GCD(5, 824) = ( 5 x 824 ) / 4120
GCD(5, 824) = 4120 / 4120
GCD(5, 824) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 894
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 894) = 894
GCD(1, 894) = ( 1 x 894 ) / 894
GCD(1, 894) = 894 / 894
GCD(1, 894) = 1
GCD of 640, 505, 824, 894 is 1
