Greatest Common Divisior
We found the divisors of 647, 989, 389, 147 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 647, 989, 389, 147 is 1.
Therefore, GCD of numbers 647, 989, 389, 147 is 1
Given Input Data is 647, 989, 389, 147
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 647 is 647
Prime Factorization of 989 is 23 x 43
Prime Factorization of 389 is 389
Prime Factorization of 147 is 3 x 7 x 7
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(647, 989) = 639883
GCD(647, 989) = ( 647 x 989 ) / 639883
GCD(647, 989) = 639883 / 639883
GCD(647, 989) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 389
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 389) = 389
GCD(1, 389) = ( 1 x 389 ) / 389
GCD(1, 389) = 389 / 389
GCD(1, 389) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 147
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 147) = 147
GCD(1, 147) = ( 1 x 147 ) / 147
GCD(1, 147) = 147 / 147
GCD(1, 147) = 1
GCD of 647, 989, 389, 147 is 1
