1, 17, 41, 697
Greatest Common Divisior
We found the divisors of 345, 448, 85, 697 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 345, 448, 85, 697 is 1.
Therefore, GCD of numbers 345, 448, 85, 697 is 1
Given Input Data is 345, 448, 85, 697
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 345 is 3 x 5 x 23
Prime Factorization of 448 is 2 x 2 x 2 x 2 x 2 x 2 x 7
Prime Factorization of 85 is 5 x 17
Prime Factorization of 697 is 17 x 41
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(345, 448) = 154560
GCD(345, 448) = ( 345 x 448 ) / 154560
GCD(345, 448) = 154560 / 154560
GCD(345, 448) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 85
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 85) = 85
GCD(1, 85) = ( 1 x 85 ) / 85
GCD(1, 85) = 85 / 85
GCD(1, 85) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 697
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 697) = 697
GCD(1, 697) = ( 1 x 697 ) / 697
GCD(1, 697) = 697 / 697
GCD(1, 697) = 1
GCD of 345, 448, 85, 697 is 1
