Greatest Common Divisior
We found the divisors of 615, 159, 971, 863 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 615, 159, 971, 863 is 1.
Therefore, GCD of numbers 615, 159, 971, 863 is 1
Given Input Data is 615, 159, 971, 863
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 615 is 3 x 5 x 41
Prime Factorization of 159 is 3 x 53
Prime Factorization of 971 is 971
Prime Factorization of 863 is 863
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(615, 159) = 32595
GCD(615, 159) = ( 615 x 159 ) / 32595
GCD(615, 159) = 97785 / 32595
GCD(615, 159) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 971
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 971) = 2913
GCD(3, 971) = ( 3 x 971 ) / 2913
GCD(3, 971) = 2913 / 2913
GCD(3, 971) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 863
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 863) = 863
GCD(1, 863) = ( 1 x 863 ) / 863
GCD(1, 863) = 863 / 863
GCD(1, 863) = 1
GCD of 615, 159, 971, 863 is 1
