Greatest Common Divisior
We found the divisors of 863, 771, 20, 636 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 863, 771, 20, 636 is 1.
Therefore, GCD of numbers 863, 771, 20, 636 is 1
Given Input Data is 863, 771, 20, 636
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 863 is 863
Prime Factorization of 771 is 3 x 257
Prime Factorization of 20 is 2 x 2 x 5
Prime Factorization of 636 is 2 x 2 x 3 x 53
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(863, 771) = 665373
GCD(863, 771) = ( 863 x 771 ) / 665373
GCD(863, 771) = 665373 / 665373
GCD(863, 771) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 20
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 20) = 20
GCD(1, 20) = ( 1 x 20 ) / 20
GCD(1, 20) = 20 / 20
GCD(1, 20) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 636
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 636) = 636
GCD(1, 636) = ( 1 x 636 ) / 636
GCD(1, 636) = 636 / 636
GCD(1, 636) = 1
GCD of 863, 771, 20, 636 is 1
