Greatest Common Divisior
We found the divisors of 644, 987, 260 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 644, 987, 260 is 1.
Therefore, GCD of numbers 644, 987, 260 is 1
Given Input Data is 644, 987, 260
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 644 is 2 x 2 x 7 x 23
Prime Factorization of 987 is 3 x 7 x 47
Prime Factorization of 260 is 2 x 2 x 5 x 13
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(644, 987) = 90804
GCD(644, 987) = ( 644 x 987 ) / 90804
GCD(644, 987) = 635628 / 90804
GCD(644, 987) = 7
Step2:
Here we consider the GCD from the above i.e. 7 as first number and the next as 260
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(7, 260) = 1820
GCD(7, 260) = ( 7 x 260 ) / 1820
GCD(7, 260) = 1820 / 1820
GCD(7, 260) = 1
GCD of 644, 987, 260 is 1
