Greatest Common Divisior
We found the divisors of 530, 897, 77, 655 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 530, 897, 77, 655 is 1.
Therefore, GCD of numbers 530, 897, 77, 655 is 1
Given Input Data is 530, 897, 77, 655
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 897 is 3 x 13 x 23
Prime Factorization of 77 is 7 x 11
Prime Factorization of 655 is 5 x 131
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, 897) = 475410
GCD(530, 897) = ( 530 x 897 ) / 475410
GCD(530, 897) = 475410 / 475410
GCD(530, 897) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 77
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 77) = 77
GCD(1, 77) = ( 1 x 77 ) / 77
GCD(1, 77) = 77 / 77
GCD(1, 77) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 655
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 655) = 655
GCD(1, 655) = ( 1 x 655 ) / 655
GCD(1, 655) = 655 / 655
GCD(1, 655) = 1
GCD of 530, 897, 77, 655 is 1
