Greatest Common Divisior
We found the divisors of 653, 390, 28, 911 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 653, 390, 28, 911 is 1.
Therefore, GCD of numbers 653, 390, 28, 911 is 1
Given Input Data is 653, 390, 28, 911
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 653 is 653
Prime Factorization of 390 is 2 x 3 x 5 x 13
Prime Factorization of 28 is 2 x 2 x 7
Prime Factorization of 911 is 911
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(653, 390) = 254670
GCD(653, 390) = ( 653 x 390 ) / 254670
GCD(653, 390) = 254670 / 254670
GCD(653, 390) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 28
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 28) = 28
GCD(1, 28) = ( 1 x 28 ) / 28
GCD(1, 28) = 28 / 28
GCD(1, 28) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 911
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 911) = 911
GCD(1, 911) = ( 1 x 911 ) / 911
GCD(1, 911) = 911 / 911
GCD(1, 911) = 1
GCD of 653, 390, 28, 911 is 1
