Greatest Common Divisior
We found the divisors of 676, 560, 947, 620 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 676, 560, 947, 620 is 1.
Therefore, GCD of numbers 676, 560, 947, 620 is 1
Given Input Data is 676, 560, 947, 620
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 676 is 2 x 2 x 13 x 13
Prime Factorization of 560 is 2 x 2 x 2 x 2 x 5 x 7
Prime Factorization of 947 is 947
Prime Factorization of 620 is 2 x 2 x 5 x 31
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(676, 560) = 94640
GCD(676, 560) = ( 676 x 560 ) / 94640
GCD(676, 560) = 378560 / 94640
GCD(676, 560) = 4
Step2:
Here we consider the GCD from the above i.e. 4 as first number and the next as 947
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(4, 947) = 3788
GCD(4, 947) = ( 4 x 947 ) / 3788
GCD(4, 947) = 3788 / 3788
GCD(4, 947) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 620
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
GCD(1, 620) = 620 / 620
GCD(1, 620) = 1
GCD of 676, 560, 947, 620 is 1
