Greatest Common Divisior
We found the divisors of 286, 630, 639 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 286, 630, 639 is 1.
Therefore, GCD of numbers 286, 630, 639 is 1
Given Input Data is 286, 630, 639
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 286 is 2 x 11 x 13
Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7
Prime Factorization of 639 is 3 x 3 x 71
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(286, 630) = 90090
GCD(286, 630) = ( 286 x 630 ) / 90090
GCD(286, 630) = 180180 / 90090
GCD(286, 630) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 639
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 639) = 1278
GCD(2, 639) = ( 2 x 639 ) / 1278
GCD(2, 639) = 1278 / 1278
GCD(2, 639) = 1
GCD of 286, 630, 639 is 1
