Greatest Common Divisior
We found the divisors of 238, 693, 909, 630 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 238, 693, 909, 630 is 1.
Therefore, GCD of numbers 238, 693, 909, 630 is 1
Given Input Data is 238, 693, 909, 630
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 238 is 2 x 7 x 17
Prime Factorization of 693 is 3 x 3 x 7 x 11
Prime Factorization of 909 is 3 x 3 x 101
Prime Factorization of 630 is 2 x 3 x 3 x 5 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(238, 693) = 23562
GCD(238, 693) = ( 238 x 693 ) / 23562
GCD(238, 693) = 164934 / 23562
GCD(238, 693) = 7
Step2:
Here we consider the GCD from the above i.e. 7 as first number and the next as 909
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(7, 909) = 6363
GCD(7, 909) = ( 7 x 909 ) / 6363
GCD(7, 909) = 6363 / 6363
GCD(7, 909) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 630
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 630) = 630
GCD(1, 630) = ( 1 x 630 ) / 630
GCD(1, 630) = 630 / 630
GCD(1, 630) = 1
GCD of 238, 693, 909, 630 is 1
