Greatest Common Divisior
We found the divisors of 20, 636, 527, 127 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 20, 636, 527, 127 is 1.
Therefore, GCD of numbers 20, 636, 527, 127 is 1
Given Input Data is 20, 636, 527, 127
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 20 is 2 x 2 x 5
Prime Factorization of 636 is 2 x 2 x 3 x 53
Prime Factorization of 527 is 17 x 31
Prime Factorization of 127 is 127
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(20, 636) = 3180
GCD(20, 636) = ( 20 x 636 ) / 3180
GCD(20, 636) = 12720 / 3180
GCD(20, 636) = 4
Step2:
Here we consider the GCD from the above i.e. 4 as first number and the next as 527
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(4, 527) = 2108
GCD(4, 527) = ( 4 x 527 ) / 2108
GCD(4, 527) = 2108 / 2108
GCD(4, 527) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 127
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 127) = 127
GCD(1, 127) = ( 1 x 127 ) / 127
GCD(1, 127) = 127 / 127
GCD(1, 127) = 1
GCD of 20, 636, 527, 127 is 1
