Greatest Common Divisior
We found the divisors of 495, 289, 70, 105 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 495, 289, 70, 105 is 1.
Therefore, GCD of numbers 495, 289, 70, 105 is 1
Given Input Data is 495, 289, 70, 105
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 495 is 3 x 3 x 5 x 11
Prime Factorization of 289 is 17 x 17
Prime Factorization of 70 is 2 x 5 x 7
Prime Factorization of 105 is 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(495, 289) = 143055
GCD(495, 289) = ( 495 x 289 ) / 143055
GCD(495, 289) = 143055 / 143055
GCD(495, 289) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 70
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 70) = 70
GCD(1, 70) = ( 1 x 70 ) / 70
GCD(1, 70) = 70 / 70
GCD(1, 70) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 105
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 105) = 105
GCD(1, 105) = ( 1 x 105 ) / 105
GCD(1, 105) = 105 / 105
GCD(1, 105) = 1
GCD of 495, 289, 70, 105 is 1
