Greatest Common Divisior
We found the divisors of 247, 421, 139, 906 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 247, 421, 139, 906 is 1.
Therefore, GCD of numbers 247, 421, 139, 906 is 1
Given Input Data is 247, 421, 139, 906
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 247 is 13 x 19
Prime Factorization of 421 is 421
Prime Factorization of 139 is 139
Prime Factorization of 906 is 2 x 3 x 151
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(247, 421) = 103987
GCD(247, 421) = ( 247 x 421 ) / 103987
GCD(247, 421) = 103987 / 103987
GCD(247, 421) = 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 906
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 906) = 906
GCD(1, 906) = ( 1 x 906 ) / 906
GCD(1, 906) = 906 / 906
GCD(1, 906) = 1
GCD of 247, 421, 139, 906 is 1
