1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
Greatest Common Divisior
We found the divisors of 127, 389, 139, 620 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 127, 389, 139, 620 is 1.
Therefore, GCD of numbers 127, 389, 139, 620 is 1
Given Input Data is 127, 389, 139, 620
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 127 is 127
Prime Factorization of 389 is 389
Prime Factorization of 139 is 139
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(127, 389) = 49403
GCD(127, 389) = ( 127 x 389 ) / 49403
GCD(127, 389) = 49403 / 49403
GCD(127, 389) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 139
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
GCD(1, 139) = 139 / 139
GCD(1, 139) = 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 127, 389, 139, 620 is 1
