Greatest Common Divisior
We found the divisors of 278, 515, 32, 189 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 278, 515, 32, 189 is 1.
Therefore, GCD of numbers 278, 515, 32, 189 is 1
Given Input Data is 278, 515, 32, 189
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 278 is 2 x 139
Prime Factorization of 515 is 5 x 103
Prime Factorization of 32 is 2 x 2 x 2 x 2 x 2
Prime Factorization of 189 is 3 x 3 x 3 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(278, 515) = 143170
GCD(278, 515) = ( 278 x 515 ) / 143170
GCD(278, 515) = 143170 / 143170
GCD(278, 515) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 32
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 32) = 32
GCD(1, 32) = ( 1 x 32 ) / 32
GCD(1, 32) = 32 / 32
GCD(1, 32) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 189
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 189) = 189
GCD(1, 189) = ( 1 x 189 ) / 189
GCD(1, 189) = 189 / 189
GCD(1, 189) = 1
GCD of 278, 515, 32, 189 is 1
