Greatest Common Divisior
We found the divisors of 645, 968, 322, 980 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 645, 968, 322, 980 is 1.
Therefore, GCD of numbers 645, 968, 322, 980 is 1
Given Input Data is 645, 968, 322, 980
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 645 is 3 x 5 x 43
Prime Factorization of 968 is 2 x 2 x 2 x 11 x 11
Prime Factorization of 322 is 2 x 7 x 23
Prime Factorization of 980 is 2 x 2 x 5 x 7 x 7
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(645, 968) = 624360
GCD(645, 968) = ( 645 x 968 ) / 624360
GCD(645, 968) = 624360 / 624360
GCD(645, 968) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 322
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 322) = 322
GCD(1, 322) = ( 1 x 322 ) / 322
GCD(1, 322) = 322 / 322
GCD(1, 322) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 980
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 980) = 980
GCD(1, 980) = ( 1 x 980 ) / 980
GCD(1, 980) = 980 / 980
GCD(1, 980) = 1
GCD of 645, 968, 322, 980 is 1
