1, 337
Greatest Common Divisior
We found the divisors of 438, 879, 28, 337 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 438, 879, 28, 337 is 1.
Therefore, GCD of numbers 438, 879, 28, 337 is 1
Given Input Data is 438, 879, 28, 337
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 438 is 2 x 3 x 73
Prime Factorization of 879 is 3 x 293
Prime Factorization of 28 is 2 x 2 x 7
Prime Factorization of 337 is 337
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(438, 879) = 128334
GCD(438, 879) = ( 438 x 879 ) / 128334
GCD(438, 879) = 385002 / 128334
GCD(438, 879) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 28
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 28) = 84
GCD(3, 28) = ( 3 x 28 ) / 84
GCD(3, 28) = 84 / 84
GCD(3, 28) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 337
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 337) = 337
GCD(1, 337) = ( 1 x 337 ) / 337
GCD(1, 337) = 337 / 337
GCD(1, 337) = 1
GCD of 438, 879, 28, 337 is 1
