Greatest Common Divisior
We found the divisors of 530, 170, 488, 155 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 530, 170, 488, 155 is 1.
Therefore, GCD of numbers 530, 170, 488, 155 is 1
Given Input Data is 530, 170, 488, 155
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 530 is 2 x 5 x 53
Prime Factorization of 170 is 2 x 5 x 17
Prime Factorization of 488 is 2 x 2 x 2 x 61
Prime Factorization of 155 is 5 x 31
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(530, 170) = 9010
GCD(530, 170) = ( 530 x 170 ) / 9010
GCD(530, 170) = 90100 / 9010
GCD(530, 170) = 10
Step2:
Here we consider the GCD from the above i.e. 10 as first number and the next as 488
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(10, 488) = 2440
GCD(10, 488) = ( 10 x 488 ) / 2440
GCD(10, 488) = 4880 / 2440
GCD(10, 488) = 2
Step3:
Here we consider the GCD from the above i.e. 2 as first number and the next as 155
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 155) = 310
GCD(2, 155) = ( 2 x 155 ) / 310
GCD(2, 155) = 310 / 310
GCD(2, 155) = 1
GCD of 530, 170, 488, 155 is 1
