Greatest Common Divisior
We found the divisors of 427, 966, 55, 620 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 427, 966, 55, 620 is 1.
Therefore, GCD of numbers 427, 966, 55, 620 is 1
Given Input Data is 427, 966, 55, 620
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 427 is 7 x 61
Prime Factorization of 966 is 2 x 3 x 7 x 23
Prime Factorization of 55 is 5 x 11
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(427, 966) = 58926
GCD(427, 966) = ( 427 x 966 ) / 58926
GCD(427, 966) = 412482 / 58926
GCD(427, 966) = 7
Step2:
Here we consider the GCD from the above i.e. 7 as first number and the next as 55
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(7, 55) = 385
GCD(7, 55) = ( 7 x 55 ) / 385
GCD(7, 55) = 385 / 385
GCD(7, 55) = 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 427, 966, 55, 620 is 1
