Greatest Common Divisior
We found the divisors of 290, 864, 10, 639 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 290, 864, 10, 639 is 1.
Therefore, GCD of numbers 290, 864, 10, 639 is 1
Given Input Data is 290, 864, 10, 639
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 290 is 2 x 5 x 29
Prime Factorization of 864 is 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3
Prime Factorization of 10 is 2 x 5
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(290, 864) = 125280
GCD(290, 864) = ( 290 x 864 ) / 125280
GCD(290, 864) = 250560 / 125280
GCD(290, 864) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 10
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 10) = 10
GCD(2, 10) = ( 2 x 10 ) / 10
GCD(2, 10) = 20 / 10
GCD(2, 10) = 2
Step3:
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 290, 864, 10, 639 is 1
