1, 5, 11, 25, 55, 275
Greatest Common Divisior
We found the divisors of 648, 139, 64, 275 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 648, 139, 64, 275 is 1.
Therefore, GCD of numbers 648, 139, 64, 275 is 1
Given Input Data is 648, 139, 64, 275
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 648 is 2 x 2 x 2 x 3 x 3 x 3 x 3
Prime Factorization of 139 is 139
Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2
Prime Factorization of 275 is 5 x 5 x 11
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(648, 139) = 90072
GCD(648, 139) = ( 648 x 139 ) / 90072
GCD(648, 139) = 90072 / 90072
GCD(648, 139) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 64
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 64) = 64
GCD(1, 64) = ( 1 x 64 ) / 64
GCD(1, 64) = 64 / 64
GCD(1, 64) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 275
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 275) = 275
GCD(1, 275) = ( 1 x 275 ) / 275
GCD(1, 275) = 275 / 275
GCD(1, 275) = 1
GCD of 648, 139, 64, 275 is 1
