Greatest Common Divisior
We found the divisors of 645, 202, 486, 279 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 645, 202, 486, 279 is 1.
Therefore, GCD of numbers 645, 202, 486, 279 is 1
Given Input Data is 645, 202, 486, 279
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 645 is 3 x 5 x 43
Prime Factorization of 202 is 2 x 101
Prime Factorization of 486 is 2 x 3 x 3 x 3 x 3 x 3
Prime Factorization of 279 is 3 x 3 x 31
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(645, 202) = 130290
GCD(645, 202) = ( 645 x 202 ) / 130290
GCD(645, 202) = 130290 / 130290
GCD(645, 202) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 486
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 486) = 486
GCD(1, 486) = ( 1 x 486 ) / 486
GCD(1, 486) = 486 / 486
GCD(1, 486) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 279
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 279) = 279
GCD(1, 279) = ( 1 x 279 ) / 279
GCD(1, 279) = 279 / 279
GCD(1, 279) = 1
GCD of 645, 202, 486, 279 is 1
