Greatest Common Divisior
We found the divisors of 445, 770, 68, 162 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 445, 770, 68, 162 is 1.
Therefore, GCD of numbers 445, 770, 68, 162 is 1
Given Input Data is 445, 770, 68, 162
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 445 is 5 x 89
Prime Factorization of 770 is 2 x 5 x 7 x 11
Prime Factorization of 68 is 2 x 2 x 17
Prime Factorization of 162 is 2 x 3 x 3 x 3 x 3
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(445, 770) = 68530
GCD(445, 770) = ( 445 x 770 ) / 68530
GCD(445, 770) = 342650 / 68530
GCD(445, 770) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 68
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 68) = 340
GCD(5, 68) = ( 5 x 68 ) / 340
GCD(5, 68) = 340 / 340
GCD(5, 68) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 162
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 162) = 162
GCD(1, 162) = ( 1 x 162 ) / 162
GCD(1, 162) = 162 / 162
GCD(1, 162) = 1
GCD of 445, 770, 68, 162 is 1
