Greatest Common Divisior
We found the divisors of 631, 620, 530, 870 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 631, 620, 530, 870 is 1.
Therefore, GCD of numbers 631, 620, 530, 870 is 1
Given Input Data is 631, 620, 530, 870
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 631 is 631
Prime Factorization of 620 is 2 x 2 x 5 x 31
Prime Factorization of 530 is 2 x 5 x 53
Prime Factorization of 870 is 2 x 3 x 5 x 29
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(631, 620) = 391220
GCD(631, 620) = ( 631 x 620 ) / 391220
GCD(631, 620) = 391220 / 391220
GCD(631, 620) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 530
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 530) = 530
GCD(1, 530) = ( 1 x 530 ) / 530
GCD(1, 530) = 530 / 530
GCD(1, 530) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 870
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 870) = 870
GCD(1, 870) = ( 1 x 870 ) / 870
GCD(1, 870) = 870 / 870
GCD(1, 870) = 1
GCD of 631, 620, 530, 870 is 1
