1, 3, 179, 537
Greatest Common Divisior
We found the divisors of 438, 261, 537 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 438, 261, 537 is 3.
Therefore, GCD of numbers 438, 261, 537 is 3
Given Input Data is 438, 261, 537
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 261 is 3 x 3 x 29
Prime Factorization of 537 is 3 x 179
Highest common occurrences in the given inputs are 31
Multiplying them we get the GCD as 3
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, 261) = 38106
GCD(438, 261) = ( 438 x 261 ) / 38106
GCD(438, 261) = 114318 / 38106
GCD(438, 261) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 537
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 537) = 537
GCD(3, 537) = ( 3 x 537 ) / 537
GCD(3, 537) = 1611 / 537
GCD(3, 537) = 3
GCD of 438, 261, 537 is 3
